Hello Todd,
thank you for your comments.
I did not have time yet to follow your suggestions (I certainly will).

However, yesterday I was able to make some progress with respect to the Intel
board DQ45CB that
solves most of my problems.
It seems that most problems were caused by the board and not Xen!
I think it is important to share my new experience as early as possible in
order to prevent others for
suffering in vain or doing unneccessary error analysis.
Some days ago Intel put a new firmware for the board onto their WEB-site
CBQ4510H.86A.0061.BI.ZIP
I upgraded my board from CBQ4510H.86A.0059 with that new BIOS and the following
problems seem to have vanished:
Summary:
========
Update to BIOS CBQ4510H.86A.0061.BI.ZIP solved the following issues:
- Whenever I boot my Xen 2.6.18.8 (Xen 3.3) with kernel parameter iommu=1
the boot process freezes.
SOLVED (details below)
and related to that
- VT-d broken. No PCI backend hiding with HVM guest possible
SOLVED (details below)
- When I insert a PCIe x16 Graphics card (ATI Radeon HD 2400 Pro) the BIOS menu
display
somehow becomes slow. The experience is like if you use a 300 Baut serial line
connection.
SOLVED (details below)
- PCIe x16 graphics with Xen kernel broken
SOLVED (details below)
I will also post the above short note on xen-devel

My current setup:
Xen Source: http://bits.xensource.com/oss-xen/release/3.3.0/xen-3.3.0.tar.gz
Xen Kernel: hg clone http://xenbits.xensource.com/linux-2.6.18-xen.hg
Details for the solved issues:
======================
- Whenever I boot my Xen 2.6.18.8 (Xen 3.3) with kernel parameter iommu=1
the boot process freezes. (SOLVED)
After the BIOS update the Xen kernel boots without problems even if I use the
iommu=1
#----------------------------
- VT-d broken. No PCI backend hiding with HVM guest possible (SOLVED)
PCI backend hideing and VT-d seem to work now!
The functionality 'pciback' is compiled fixed into my kernel (not a module).
I use the following grub config
title Xen 3.3.0 / kernel 2.6.18.8-xen with IOMMU=1 and backhide 1G NIC

module /vmlinuz-2.6.18.8-xen root=/dev/mapper/RootVG-root ro
pciback.hide=(03:00.0)
module /initrd-2.6.18.8-xen.img
The messages/dmesg show
kernel: Bootdata ok (command line is root=/dev/mapper/RootVG-root ro
pciback.hide=(03:00.0))
...

In the config of the HVM WinXP guest I use:
pci=[ '03:00.0' ]
In the running guest I see a new (native) 1Gbit NIC.
I did not do any performance test yet.
However the VT-d/PCI backend hide mechanism seems to work :-)
#----------------------------
- When I insert a PCIe x16 Graphics card (ATI Radeon HD 2400 Pro) the BIOS menu
display
somehow becomes slow. The experience is like if you use a 300 Baut serial line
connection.
(SOLVED)
Details see next paragraph
- PCIe x16 graphics with Xen kernel broken
SOLVED
After the BIOS update I tested two PCIe x16 graphics adapters:
- ATI Radeon HD 2400 Pro
- MSI NX 8400GS (Nvidia 8400GS)
Both cards run now without problems on a non-Xen standard Debian etch 2.6.18.6
kernel.
Especially, the BIOS menus are no longer slowed down.
3D runs perfectly with the propriatary drivers
ATI: ati-driver-installer-8-5-x86.x86_64.run
NVIDIA: NVIDIA-Linux-x86_64-177.80-pkg2.run
Caveat: after testing the Nvida Card/Driver you need to remove some links that
point to
NVIDIA drivers before you test again the ATI card/driver.
Search /usr/lib for files like with '*177.80*' in them.
With the xen-kernel 2.6.18.8 booted (details about version above) I was able to
configure the ATI card for X11
by using the ATI driver ati-driver-installer-8-5-x86.x86_64.run.
However, 3D s broken due to a problem with symbols
Oct 27 10:09:09 susi kernel: fglrx: Unknown symbol xen_invlpg_mask
With the xen-kernel 2.6.18.8 booted (details about version above) I was not
able to compile the NVIDIA driver
NVIDIA-Linux-x86_64-177.80-pkg2.run
The build script from NVIDIA expclicitly states that it won't not run on a
XEN-kernel
#-----------------------
Details about BIOS update
I download the archive
CBQ4510H.86A.0061.BI.ZIP
from the Intel page
I had quite some hard time to install the update via the DOS-Utility IFLASH.EXE
on a host without FD-drive
and only linux installed on the HDs. After frantically searching for some old
Win boot media I came up with
a good old Win98SE2 boot CD. It has the nice feature to recognize USB sticks as
FD disk drive B:
Then I proceeded as follows.
(Shame on me that I do not know how to do it better with purely Linux and
freeDos basis
Is anybody out there who can educate me?)
Unpack the zip archive.
This yields
CB0061.BIO
CB0061.ITK
IFLASH.EXE
Copy these files to a USB stick with FAT FS
Reboot the host and enter BIOS
Set Advanced/Drives Disk mode from RAID to IDE
This allows for a proper Win98SE2 boot from CD
Boot a Win98SE2 CD.
It will recognize the USB stick as drive b:
b:
iflash /PF CB0061.BIO
When prompted
- remove CD
- remove USB stick
type return an wait until BIOS flash has finished
It takes about 3-5 minutes
