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.
