Mesa 7.6.0 bugs

[Bojan Smojver]

New mesa (7.6.0) is causing trouble for people using F-11/12 code (see
bugs #524338 and #509528 for instance).

Are there fixes available for these problems? Last time 7.6.0 packages
were built was Sept 21, which is a month and a half ago and it seems
that concerns from the above bugs are not being addressed.

Is it too late to revert to 7.5.x, which used to work fine?
