RAM upgrade ignored or kernel panic arises on Thinkpad T22
Running Debian Woody Kernel 2.4.18 on an IBM Thinkpad T-22.

Windows XP recognizes new RAM, and apparently has no difficulties with

Could it be that I may have accidentally limit my kernel to 128M during
Deleting (via rescue disk) the added line eliminates the kernel panic,

the upgraded memory with Linux.
Much "googling" has not produced a solution.
Thanks for your help.
