--- Comment #4 from kowalski marcin yoshi314@gmail.com 2012-07-01 12:45:49 CDT --- a small correction, i am not yet using a git build of mesa for 32bit opengl drivers, but stable 32bit libraries gentoo linux offers for multilib x86-64 setups.
I'm just getting around to test it on current git of mesa. If there are any changes in behavior, i'll post about it.
