I have got a repo for wheezy with latest mesa code but as it is build from mesa git experimental and there was never a package released in experimental it has got a bug that you can not switch to binary drivers as long as you use the new mesa code. Last night i at least figured out why building opengl apps did not work with it, i only applied a hotfix for that. So basically you can get latest mesa code... You find instructions in irc://irc.freenode.net/#kanotix when you ask the bot for !mesa . With it Team Fortress 2 runs fine with Ivy Bridge even at 1920x1200. Trine 2 is a bit slow but you can play it (faster as with mesa 8). Killing Floor works (but worked with mesa 8.0.5 as well). Serious Sam 3 does NOT work. No idea what would happen with Radeon drivers, did not test em lately. Maybe i test a r500 card sooner or later.
