--- Comment #4 from Dave Airlie airlied@freedesktop.org 2010-12-11 20:23:28 PST --- radeonCreatescreen is only called in DRI1 system,
radeonCreateScreen2 is called on DRI2 systems.
You can only have a version 1.x driver with a DRI1 system and a version 2.x driver with a DRI2 system.
Short of hacking things to force some wierd codepaths you can't cross the streams.
