I could be wrong, (in fact I'm very likely wrong), but I don't think 
the video card needs an IRQ. My card had IRQ 9 (I think) which was
by default disabled and I've left it that way and not had a problem.
From the way I understand it, communication is only in one direction,
the application (X or otherwise) writing to the card, so there is
no reason for an interrupt since the card never gives data back.
