I've got a sparcserver 20, currently with a single Supersparc proc on
it. Can I put different kinds of processors on the SBUS, or do they
all have to be identical to the already install proc? And if I can
install different procs, what's the highest level proc I can throw in
there?

This is a complex and messy issue.
Goto http://www.sunhelp.org/ and find the hardware FAQ.
Under processors you will find a messy matrix with a lot of
footnotes.

Basically it depends on the processor models and the OBP revision.

Or, to be on the safe side, if you are going multiprocessor make sure
to use processors of equal type.
