Comment # 137 on bug 60879 from madmalkav

I have been testing and commenting my results on the IRC channel, didn't
mention anything here as nothing interesting happened.

Blacklisting the module bears no difference. I can upload logs if needed but
they are the same just without the fglrx lines.

Also, I'm trying to repeat the tests of the user in comment #104 but I'm
totally unable to get any debug message I insert in si_state.c to show on any
log. Any tips or a link to some form of "Mesa debugging for dummies" will be
gladly appreciate.
