i posted a while back about devfs not being able to find my scsi disk, i'm
posting some info that might be useful.
i think this is a problem because i did some funky stuff when i labled it,
however, mount CAN find the disk in a non-devfs system.

ok, heh :) now what?
i know i musta done something icky for me to be able to mount it normally
