Panic on boot on Lenovo ThinkCentre,
before copyright message appears

I've been having trouble getting 6.x, 7.x and 8.0 to boot on a Lenovo
ThinkCentre M-series, model 6081 AG1. The system panics on boot, what
seems to be as soon as it goes to boot the kernel (it loads the kernel
and modules like acpi.ko fine)...
System is running the latest BIOS (2KRT50AUS) from 22 July 2008; we have
successfully booted Windows and Linux on the same system, and it has
survived several hours of memtest'ing.
The panic (manually transcribed, so I hope I haven't made any typos) as
seen from the 200807/i386 snapshot CD:

Is there any additional information I can provide from the DDB prompt
that may help tracking down why this machine is unable to boot (I have
included the output from backtrace above, but it does not appear to help
much...)?
Cheers
