a boot disk that the install created won't help, your root filesystem
is corrupt.

It sounds like your filesystem was corrupted when you got the kernel
panic. You may not be able to salvage the system without a fair
amount of work. Some things to try:
- boot into the installer (rescue.bin and root.bin) and manually mount
the currupted root filesystem. Try chroot'ing into it and see what
breaks. Do you have a working shell? Maybe install a statically
linked shell (busybox-static will do the job).
- now that you have a shell working you can boot normally and pass
init=/bin/sh to the kernel. This will bypass the normall process of
starting up userspace with /sbin/init. The theory is that
/sbin/init (or a library it depends on) is broken.
- Once you have a shell trying bringing up the network manually, then
apt-get install --reinstall the broken packages. That still might
not work if the dpkg database is too broken.
Good luck,
David
