I can try.  Of course transscribing them by hand is a pain.  I wonder
if the serial port works on this thing, so I can make grub use that
(assuming I can get grub to load itself first, before hitting the
BIOS bug.  I might be able to.)

It's a VERY old 80G WD SATA drive.  No 4k sectors here.

By the way, making the partition smaller than 8G made it boot just
fine, so it seems the BIOS is failing with higher sector numbers only.
That's simply pathetic.
