My suggestions.
1) setup to use the external etherboot, and the linuxbios elf loader,
   it keeps you from being stuck with just loading Linux.
2) Load memtest86 and see if you memory appears o.k.
3) Get an oops that reports something, without running ksyms oops on
   the output I have no idea.  Where in the kernel you are crashing.

The best clue you have given is:

It looks like there is something fishy in your hard drive code.

I don't have any direct experience with the VIA 694X, so I don't know
which kinds of things are likely to go wrong.

I am forwarding this to the LinuxBIOS list in case someone else has a clue.

boot the kernel 2.4.19 from linuxbios

[Ronald G Minnich]

I think I would like to see this output:
> Partition check:
>  hda: [PTBL] [1869/255/63] hda1 hda2 hda3

Is it identical under the normal bios?

What does the normal BIOS show? Many times this problem occurs with weird
hard drive PTBL setups.

I assume your hard drive is:
hda1 -> /boot
hda2 -> /
hda3 -> swap
