Hi Joe,
   OK - I got USB working and with the append="init=/bin/bash" in I
can at least do cd and ls commands.

   All the devices you asked about exist - /dev/hda1 through 20,
/dev/hdb1 through 20, /dev/null and /dev/zero - all exist.

   Doing know if it's a clue but in this  append="init=/bin/bash"
state I was unable to do a reboot or a shutdown as it complained about
missing initctl I think?

   Being that I made a number of changes to the kernel config to get
USB working I remove the append line from yaboot.conf and tried
booting into Gentoo proper but it's still stopping at the same place
with the same message about no mtab file.

   I'll put the append back in and wait for further ideas.

   Thanks for sticking with me!

Cheers,
Mark
