[Thinkpad] A31p with 1GB RAM and Linux anybody?

Hi,

I've upgraded today my A31p from 768MB to 1GB. Not a pleasant
experience I may say. I'm running SuSE Linux 8.2 with an 2.4.22 kernel
and encountered several problems:

Phase I: Kernel has only up to 1GB support

* 1GB + USB (RF Mouse) -> BOOM
* 1GB all peripherals detached -> 900MB seen (seemed stable but
  haven't tested it very thoroughly)

Phase II compiled Kernel with 4GB support

* 1024MB seen, but segmentation faults
  recompiled and cross-checked all modules too

* segmentation faults

* Inserted the old 256MB module instead of the 512MB module (both
  original IBM parts - made by Infineon)
  -> Still boom/segmentation faults.

Puzzled.

Linux problem(?): 4GB kernel + less than 1024MB no go?
Hardware problem(?): Why then the probs with the old 512+256MB config?

Any suggestions how to enjoy the 1GB or - at least - return to a
non-error operation with the 768MB? That was not a successfull
excursion into the world of Thinkpad upgrading...
