As was pointed out in private email to me, there was this code that just
got checked in that changed bus_setup_intr() (I should know, I spent a
half hour pounding my head against the wall wondering why some driver
code of mine suddenly wouldnt compile :).

I know of NO other reason why this would show up on old adapters all
of a sudden. Try a kernel before those changes and see.
