FYI, I noticed this recent patch from Arjan van de Ven from lkml. It's got page flipping and user-defined interrupts for i830 (for 2.4): http://marc.theaimsgroup.com/?l=linux-kernelm=103969295019388w=2 Out of curiosity, I just downloaded the i810/i815 specs. At first glance I don't see why you

Just a quick follow-up to this. It looks like Arjan's patch comes from XFree86 CVS, which got a bunch of i830 updates from Keith and David Dawes a few days ago (which explains the KW comments in Arjan's patch). I assume we'll get these into DRI with the next sync-up. Just another example of the
