Have you made a boot floppy? This is even better than a rescue disk,
as its the same kernel you installed on your machine. However, I agree
its disconcerting that you cannot get rescue to work. I do have an
idea or two (but they may be worth what you paid for them ;-)

So far so good, I think.

if you say 'ls -l /dev/sda1' what does it say? Compare that to what
you get when booted normally. (I'm grasping at straws here, but sometimes
you really want to leave no stone unturned)

I'd be surprised if that made a difference. Now, you MIGHT try
starting an install and getting to the fdisk part and mucking
around in the shell, but thats a real pain, as you usually end up
having to mknod for everything you want, and things don't work
exactly like normal, and you MUST remember to unmount everything
you mounted or it will be dirty on reboot. Altogether not a
fun thing to fool with! (But you might want to get to that just
to see if you CAN manage to mount reiserfs, if all else fails).
In any case, like I said at the start, getting a boot floppy made
would be a first priority, and check it to be sure it works. If
you are truly paranoid, make a copy by
dd if=/dev/fd0 of=/where/I/keep/floppy/images/myboot.img,
<put new blank floppy in>
dd if=/where/I/keep/floppy/images/myboot.img of=/dev/fd0
and keep it 'offsite'. And *don't* forget to write protect that
floppy! (Oh, and check the copy to make sure it works too!)
rc
p.s. an advantage of this copy method is you always have a copy
of that floppy on (hard) disk. The truly paranoid would also
put a copy of that image on all other machines they work with....
(does no good to have a copy of the boot disk you need on the
machine that you cannot boot!)
