Neither do I, but there is an unopened 1050 page book
on my desk which might contain the answer. Let me see...

...and the answer is...definitely maybe.

Try it. The card should be identified OK, that part of
the configuration space is compatible. Since Plan 9 doesn't
really use much in the way of fancy features on video
cards (especially if you use VESA) the rest of it may be
compatible enough. What would be useful is the output
of /bin/pci and the contents of the configuration space
(xd -b '#$/pci/1.0.0raw' if, for example, the card is
shown by /bin/pci to be device 1.0.0). We can work from
there.
