Well, I must admit, I turned to the dark side for the
BIOS update.  I downloaded an exe named 2ajt51a.exe
from IBM's web site and formatted a floppy disk from a
Windows computer and then ran the exe file from that
computer to make the disk a bootable BIOS upgrade
disk.  I didn't trust wine since I'm #$%ing with my BIOS.
Then I transfered that disk to my Linux-only ThinkCentre
computer and did the upgrade.  Make sure you
download the BIOS compatible with your particular
ThinkCenter computers.

Try looking at /proc/interrupts to see if it's incrementing
slower than 250 Hz.  That was the telltale signature of my problem.  I
never noticed the date go backwards... only forwards too slowly.

Good luck...
