I had same sort of problems with my crappy VAIO (which, fortunately, is
dead now). The bios did not initialize anything, and there were many
situations where it would not recover after a reboot. The most common one
was the local APIC. It was guaranteed that if I rebooted while I had used
local APIC, the BIOS would not detect the hard disk at next boot ! And if
I booted 2.6 and used the frame buffer, then I would have no screen at
next boot, which was not really a problem since it would also timeout on
the disk 10 seconds later...

Now I have a compaq (nc8000) which does not exhibit such buggy behaviour,
but you can try disabling the APIC too just in case it's a similar problem
(at least in 32 bits, I don't know if you can disable it in 64 bits mode).
