The patch that fixed the issue for us is actually a kernel patch and not a Mesa patch and as such should work regardless of what Mesa version you're using. Regarding the question on why this issue only seems to affect 32 bit kernels and not 64 bit ones, and if the proposes patch can serve as a permanent fix or is coupled with too many undesirable side-effects ... well, Michel can probably give more qualified information about that. As it stands, the patch disables write-combining and thus will probably have negative effects on performance, although I don't really notice any difference on my own machine compared to the time "when things worked fine without any patching at all" (but I'm not really running very demanding stuff). Just using a 64 bit kernel instead of going down the patch route should fix the problem without these side-effects.
