[...] compiling takes many minutes as it is.

git bisect minimizes the number of times you need to compile Mesa to isolate the change introducing the problem.

I can't estimate where it might have broken either,

Your initial report says it's working with Mesa 9.2.3 but broken with current Git, that's good enough for bisecting.

nor risk experiencing the problem too many times (given it almost brings the system down).

I don't think it's that dramatic. It sounds like the usual symptoms of the GPU repeatedly hanging and being reset by the driver.
