Hmmmm - don't know what's wrong, and I cannot really follow what's going
on behind the scenes on my own server running XenExpress.

I'll rebuild my server next week with the source-version of Xen to get
64-bit support. I'll try the PV drivers then and see what kind of weird
stuff happens. I wouldn't be too disappointed if it doesn't work - after
all the PV drivers are probably meant for XenServer only.

Cheers
