Current tinderbox regressions (video drivers)

Hi,

   > EXA: Handle separate alpha maps properly in Composite fallback
   http://cgit.freedesktop.org/xorg/xserver/commit/?id=170cf1270dff38d3cce7f5ba5b940d1c0d70eff5

Driver maintainers:  from this commit onwards, EXA requires you to pass
in -DEXA_DRIVER_KNOWN_MAJOR=3, else it'll fail to build.  If you use
Prepare/FinishAccess, UploadToScratch or ExaOffscreenSwap*, you'll need
to make other changes too.

I've attempted to fix up:
   geode, i128, mga, savage, sis

which leaves the following still broken:
   intel, nouveau, nv, radeonhd, trident

Thanks,

- Chris.
