There is your problem. For some reason the kernel is deciding that
your machine is not PCI-capable.

Rather unhelpfully, the kernel can print that message in three
different places. The files concerned are:
 linux-2.6.8.1-xen0/arch/xen/i386/pci/irq.c
 linux-2.6.8.1-xen0/arch/xen/i386/pci/legacy.c
 linux-2.6.8.1-xen0/arch/xen/i386/pci/common.c

You may want to edit the print statements to distinguish them, so that
we can see which one(s) are actually being triggered.

It looks like maybe raw_pci_ops == NULL, even though that should be
impossible! At the same time the kernel prints 'Using configuration
type Xen' it should set raw_pci_ops to a non-NULL value.
