First patch attempt by glisse (this doesn't work)

I have already discussed this issue on #radeon IRC channel with glisse and he
gave me this patch, but unfortunately it doesn't work.

After applying this patch and recompiling kernel, everything seems good (HDTV
is again properly detected by xrandr) until I try to activate HDMI output with
xrandr. After it main laptop LVDS screen get garbled and graphics system
completely freezes (but I still can SSH into system).

This is relevant error from dmesg:
