If you want working desktop you can use this patch to disable the packet that is the issue. With that mesa patch i have stable acceleration and desktop.

Thanks Jérôme! The "EQ overflowing" is gone (same stack as detailed in comment #82, except for Mesa, which is now at Git master/5eb11eb192 + the patch from attachment 103474), but I'm still stuck on the KDE loading screen, just before the desktop is drawn. After I kill X I see the three lines, I pasted in comment #83, appearing again at the end of dmesg's output. So, no luck for me yet.
