I just created a third floppy with an ext2fs on it, and shoved a bunch of 
binaries I need on it like vim, e2fsck, ls (if you really need it), dd, and so 
on.  Then, after the normal Debian boot/root duo, I execute a shell, mount 
that third floppy on /mnt, change my PATH
  export PATH="$PATH:/mnt/sbin:/mnt/bin:/mnt/usr/bin"
and then do what I need to do.

Right now, that means deploying machines by dd'ing a 'pure' harddrive to an 
empty one, editing the host-specific files, and moving on.

I thought it was 8193, but I can't check right now.
