Finding "coupled" cards could be as easy as checking if the fbdev
api returns the same busid for both fbdev's.

That would work as long as you don't have a single PCI chip providing
2 separate independant sets of heads but I agree this is very unlikely :)

I have not seen that cards but maybe is just a difference in the function
number from the busid.

Ben, you that know the internals of fbdev's, it would be difficult to
implement the busid stuff?  Maybe that info is already known by the
drivers somewhere... It could even work for sparcs with sbus or others
archs with differents buses, as the busid nomenclature is very standarized
i think.
