I just installed FC5-T3 on my computer. With the normal kernel, everthing works fine, but when I boot into the xen-hypervisor kernel, kudzu crashes and eth0 won't come up -- it says no such device. USB ports don't work either, under the xen kernel.
I think the problem has something to do with PCI under the xen kernel. Running lspci under the xen kernel returns absolutely nothing, and there is nothing in /proc/pci either. This happens with both the stock 1955 kernel and the updated 2009 kernel. It also happened with the FC4 xen kernel, which I why I went to a FC5 test distribution in the first place...
It's a desktop system, but it has a mobile Athlon XP 2800+ on a cheap PC Chips motherboard, with a SiS 760 GX northbridge and a SiS 964 southbridge.
Has anyone else seen this or know of a possible fix?

=============================================== This is the output when I run on the non-xen kernel (the xen kernel simply returns nothing for lspci):
