Uh-oh, another broken Thinkpad BIOS.

Hmm, linux-2.2.19pre4 got the "thinkpad E820 edx overwriting" for a Thinkpad 600X from Marc Joosen. The same fix also went into 2.4.0-test13-pre6, so that can't be the problem.

Could you try to boot with "mem=one MB less than the machine actually has" and see if that fixes the problem? So "mem=127M" for a 128MB machine. If that fixes the problem, I think there is a bug in the e820 BIOS memory map and you should ask IBM to fix their BIOS.
