DPM is enabled by passing radeon.dpm=1 to the kernel paramters:

root@perry64 # cat /sys/kernel/debug/dri/64/radeon_pm_info
uvd    vclk: 0 dclk: 0
power level 2    sclk: 93000 mclk: 105000 vddc: 1185 vddci: 1150
root@perry64 # cat /sys/kernel/debug/dri/64/radeon_pm_info
uvd    vclk: 0 dclk: 0
power level 0    sclk: 10000 mclk: 15000 vddc: 950 vddci: 950

And no locks since two days.
