    These patches do apply, but during kernel compilation they block depmod (without patches all compilation work).
    INSTALL /home/yimm/compilation/kernel-pm-patches/pkg/lib/firmware/radeon/RV730_me.bin
    INSTALL /home/yimm/compilation/kernel-pm-patches/pkg/lib/firmware/radeon/RV710_pfp.bin
    INSTALL /home/yimm/compilation/kernel-pm-patches/pkg/lib/firmware/radeon/RV710_me.bin
    DEPMOD 2.6.33-rc4-rc
    And nothing...
    Ideas?

      Patches can not block depmod. Just wait longer for it to finish.

        But I have already waited 15 minutes, and always at the same step; Without them, it takes 1-2 seconds
        So I will retry by waiting more time.

          First patch is already in drm-radeon-testing.

          How to check if it really downclok the gpu/memory?

              Groan... I forgot to enable kernel debugging :-(

                I enabled kernel debugging but /sys/kernel/debug/ is still empty.

                    gentoo niko # cat /sys/kernel/debug/dri/0/radeon_pm_info
                    state: PM_STATE_DISABLED
                    default engine clock: 776000 kHz
                    current engine clock: 769500 kHz
                    default memory clock: 1126000 kHz
                    current memory clock: 1125000 kHz

                    Then I loaded nexuiz after typing:

                    gentoo niko # sleep 60 && cat /sys/kernel/debug/dri/0/radeon_pm_info
                    state: PM_STATE_DISABLED
                    default engine clock: 776000 kHz
                    current engine clock: 769500 kHz
                    default memory clock: 1126000 kHz
                    current memory clock: 1125000 kHz

                    Clocks are still the same.
                    Anyway, how to change the state? What's PM_STATE_DISABLED?

                      You have to enable it using dynpm parameter (dynpm=1). You can set this on loading module time (modprobe radeon dynpm=1), or in GRUB (radeon.dynpm=1) or in /etc/modprobe.d/some.file
