Bingo!
glxgears did not work, and after setting vblank_mode=0 it started working.
Still Gnome3 wasn't workind and the radeon numbers at /proc/interrupts were
0.
Finally we tried 'noapic' that did not work and then pci=nomsi solved
the problem :D
The bug can be closed if there is nothing you can do from a packaging
perspective.
Thanks a lot!!
