I think the reason Linux is finding PCI buses 1 and 2 is because Steve
is using Xen 2.0 (which passes the bus numbers with PCI devices on them
explicitly to the Linux kernel via a hypercall since Xen hides the

Steve, I'm not sure there's a way to know from your output if Linux
found the device you need for your hard drive or not (at least not
without compiling in some debug output), but I'd try double checking
that you've compiled in SCSI and the appropriate SCSI low-level driver
for your hardware (I didn't see a "SCSI subsystem initialized" line in
the log for the kernel that didn't work).
