That's great news, thank you! I was beginning to think that I'd have to compile
my kernel from now on.

BTW, I noticed that /sys/kernel/debug/dri/0/radeon_pm_info will report "power
level 1" when /sys/devices/system/cpu/cpufreq/boost is set to 0 (with bapm
patch, didn't test the unpatched version), while it always reported "power
level 0" in my console scenario under all other circumstances. Since I could
not notice any difference in power consumption, I was wondering what this
actually means.
