ok, the following assumes you have xorg-x11-driver-video-7.4-19.4 and the
according -debug{info,source} packages installed.

Start 'gdb --args Xorg -kb', then enter the following commands; (gdb) is the
prompt, > indicates input, everything else is gdb output, please replace
strings in <> accordingly:

(gdb) set logging on
..
(gdb) break radeon_bios.c:1004
Make breakpoint pending on future shared library load?
y
Breakpoint <1> (...) pending
(gdb) break radeon_bios.c:1009
Make breakpoint pending on future shared library load?
y
Breakpoint <2> (...) pending
(gdb) commands <1>
Type commands for when breakpoint <1> is hit, one per line.
End with a line saying just "end".
p *radeon_output
c
end
(gdb) commands <2>
Type commands for when breakpoint <2> is hit, one per line.
End with a line saying just "end".
set radeon_output->HOverPlus = 40
c
end
(gdb) run


.. Check whether you get your screen lit up, and in what resolution, and also
attach the created gdb.txt.
