> BTW, MSAA may be broken and I recommend turning it off for now.

Ok, how do I do that? I'm only aware of the debug flag "msaa". My radeon(4) man
page didn't yield anything for MSAA either and a quick grep over the Mesa code
pointed only to code actually handling MSAA (or dealing with the debug flag).
