The SFB was the "Smart Frame Buffer" described in the WRL TR93/1 tech
note (I don't a have URL handy), and was on the PMAGB cards (known
as SFB as well).  I think this document describes the engine of the
PMAG-{C,D,E,F} cards (known as PX).  Useful info all the same!

We do have support for both chipsets in NetBSD but unaccelerated in each
case.  Andy Doran will correct any mistakes about the PX support, I'm
sure :-)

Cool.
