Cool, I'll take a look at the XFree tree when I get back to work, just to give people a quick idea of what I want initially, I want to use the hardware flipping as opposed to the blt we do now, and the i815 has synchronous flipping by default (the async doesn't work properly - errata to spec) which I'm hoping will get rid of my tearing issues.. while I'm at it I'll try and add the other stuff if I can ..
