AIUI, all the intel chips are capable of driving 30-bit displays. The
later generations are more flexible and faster with greater bit depth for
LUTs etc. The output driver support should (in theory) be complete, but it
hasn't been well tested due to scarcity of suitable displays.

Hmm, the render paths should work on 10bpc surfaces. Please do file bugs
for the failures.
