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.
