Try reading:

http://www.linuxhq.com/kernel/v2.3/doc/oops-tracing.txt.html

It mentions:

Patch the kernel with one of the crash dump patches. These save
data to a floppy disk or video rom or a swap partition. None of
these are standard kernel patches so you have to find and apply
them yourself. Search kernel archives for kmsgdump, lkcd and
oops+smram.

I don't know if the "dump to floppy" patch is maintained for the
2.4.0 series.
