Actually, the bug in question could not. This was discussed quite a bit
on the mailing list and on IRC. The original DRI2 interface was
deficient and could not be made to work. So I fixed it.

The change is in the DRI2 interface, and that version was changed.
Without the corresponding updates the only thing you lose is DRI2.
Reverting to DRI1 should still work. Since this affects only the Intel
driver, and we will have a fixed driver release around the same time as
the X server release, I don't think this is a catastrophic problem.
