No. The C3 lakes the CMOV (iirc) instruction and with out a patch (that
was posted long ago on this list for 2.0.6(?)) even a recompile of xen
and the kernel will not help you


But the patch
http://lists.xensource.com/archives/html/xen-users/2005-05/msg00579.html
wont do on xen 3.0.

http://lists.xensource.com/archives/html/xen-users/2005-10/msg00037.html
reports that the patch is < xen 2.0.7

Its really a pitty that xen dont work on this low-power and fanless
(silent!) cpu.

Anyone know if it's the same for M10000/13000 (bigbrother of C3)?
AFAIK the missing CMOV instr. has been fixed on those cpu's. IMBW..
Further, the VIA KN400-series chipset should be a better design than previous ones. If only they had a KN400 pro based board, since the non-pro has issues with SATA-2 disks - not that SATA-2 matters on such slowish cpu's, but newer, larger disks will likely be SATA-2 mostly.
