I downloaded (rather slowly at that -- 5kb/sec, i need dsl!) 2.5.7.
I configured it using my old config from 2.4.13-ac<something>:
cp ../linux-2.4.13-ac<something>/.config
yes ''|make oldconfig
make menuconfig
and tweaked a few things (among them, enabling preempting).
After disabling a few of the modular items that no longer worked (i2o, firewire), I built, lilo'ed, and booted...
almost.

<0>Kernel panic: Attempted to kill init!

I don't know what the error meant ("set_section_contents Bad value"), sorry.
-----
I looked at buffer.c's __get_hash_table.
In an effort to prove my complete incompetence, I threw in a printk:
printk( KERN_ERR "__get_hash_table(%p, %d, %d)\n", bdev, block, size );
i see this before the oops:
___get_hash_table(c1345120, <incremental numbers>, 4096)
___get_hash_table(c1345120, <incremental numbers>, 4096)
^^ lots of above. the 'incremental numbers' come in pairs.
___get_hash_table(c1345120, 589824, 4096) <- 0x90000
___get_hash_table(c1345120, 589824, 4096)
___get_hash_table(c1345120, 622592, 4096) <- 0x98000
___get_hash_table(c1345120, 622592, 4096)
___get_hash_table(c1345120, 655360, 4096) <- 0xA0000
___get_hash_table(c1345120, 655360, 4096)
___get_hash_table(00000000, 8210, 4096) <- 0x1FB8!? Breaks the pattern...
Unforunately, I don't seem to be able to get any more information; sorry :(
I guess it could be worse... could be trashing the partition it would be trying to load...

You need the patch below (from Oleg Drokin) to fix this oops, but there
is also a problem with the code to finish deletes and truncates after a
crash, and that causes corruption.
For now, I'd suggest commenting out both of the finish_unfinished()
calls in fs/reiserfs/super.c. I've been working on the corruption for a
few days, it's really starting to irk me. For now, I suggest commenting
out both of the finish_unfinished() in fs/reiserfs/super.c
