Hardly.  Some do.

The A2090a and A2232, also from Commodore, have dedicated CPUs on them.

PS/2s use the MCA bus, not the EISA bus.

Indeed.  And, interestingly enough, the Amiga's Zorro II bus predates both
EISA and MCA by many years.  But dedicated processors are even older than
that.  You find them occasionally on ISA (PC-AT/XT) cards.  Setting the Wayback
Machine back a notch or two, you find dedicated processors here and there on
VME, Multibus, STD bus, and even S-100 bus.  None of which have anything much 
to do with IBM.
