About all you can do is find a file owned by admin in the var partition
and delete it. That should free up some room so you can su to root. 

As a hedge against this problem in the future, it's a useful trick to
make a 100K or so junk file in /var that's owned by admin.

If you have access to the RaQ, you could also pull out the HD and mount
it as a secondary drive in another Linux box that you do have root
access on, and manually remove some files that way.
