Try booting to the miniroot. This is a "hidden" filesystem on IRIX boxes 
which contains a very small FS and OS (e.g. think TomsBRT but on a hidden 
small partition on the hard drive).

I forgot the particular invocation from the CMOS loader (it's long and 
arcane) -- see the SGI FAQ at viz.tamu.edu.

Once you get into the miniroot, you can mount the "real" filesystem (EFS 
or XFS) and edit /etc/passwd. Prepare for some pain, because vi doesn't 
know how to handle an SGI console (not in termcap). Use ed or cat.  :)
