--- Comment #13 from lei.pero at gmail.com ---
This is related to this problem, also resolution line from grub is not
respected when corruption happens, if everything is applied from commit 
55e513b978b2afc52b7cafc5bfcb0d1dc78d75f6 except radeon.h resolutin stays
properly recognized, but black only black screen is drawn, going to tty2 does
show text, and after some waiting it is possible to type login and revert
changes (packages or xorg configuration).

If it is used as patch (radeon.h.patch) and aplied to the half, same thing
happens, black screen = resolution respected, under EXA ofc. With everything
included (from below) it gets corrupted:
