I gather that you'll need a boot kernel with i386/i486/i586 (pick one)
optimisation, and that the Sidux default kernel has i686 optimisation.
This is a problem you're likely to face increasingly, I'm afraid.

No, that's not it.  It's CPU optimisation.  Your ThinkPad's CPU is
pre-Pentium Pro (686).

No.  A _different_ problem will go away with more memory.  ;->

You've diagnosed your problem incorrectly.

i686-compiled kernels aren't going to run on a machine that old.
(You'd be facing the same problem if you had a K6 CPU, by the way.)

Either a 2.6 or 2.4 kernel will work if compile for the i586 instruction
set.  Neither will work if compiled for the i686 instruction set.  See
