I just tried switching the BIOS on this PC to SATA 'combination' mode,
which I've used in the past to access the disks using the normal PIIX
IDE driver.  Unfortunately that results in a bad crash - it looks like
Xen just isn't going to work on this PC :-(

Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ide0: I/O resource 0x1F0-0x1F7 not free.
ide0: ports already in use, skipping probe
