Not really. I tried with today's sup. Sony PCG-F350 configures both a
legacy-isa-address pcic0, and cbb0/cbb1.  If I boot with a 3c5889C
plugged in, it gets attached as ep1 at pcmcia0 at pcic0, and again as
ep2 at pcmcia2 at cbb0.  They can't both work :-(, and it gobbles a
couple of IRQs for the pcic attachment.

 
Its like the old buslogic emulation of Adaptecs: we need to disable
the legcay pcic on a cbb before or during the match for the pcic, or
the (legacy-aware) cbb is gonna match a pcic, and mess up autoconfiguration.
