Unless there is another solution to the error, I'm waiting on a patch:

http://cgit.freedesktop.org/mesa/mesa/commit/?h=7.11&id=9b3ac17991b3b421591111f863f0583ef2f06a01

up stream from xorg-edgers. I contacted one of the dev's and he replied 
that it would take 1 - 2 weeks before I got it. This has been tested by 
a couple of other users with success. See prior posts:

If anyone can assist me in applying the patch before xorg-edgers, please 
let me know.
