radeon: need regression testers

[Benjamin Herrenschmidt]

Hi !

I would appreciate if people could test the patch I just added to
https://bugs.freedesktop.org/show_bug.cgi?id=3911 and tell me if it
breaks anything for them or not ? I intend to commit it to CVS but since
the radeon driver is such a mess and that patch is a bit invasive, I'd
like some regression testing. I would expect a regression to show up as
a misbehaviour right away on server launch btw. Especially, test
with/without DRI, console switch, use with/without fbdev, ...

Thanks,

Ben.
