Hi, I just tried the DPM support out on a E-450 APU (HD6320) and it did not work like expected. In the terminal everything seemed ok but when I started a display manager, the screen showed garbage and the system basically locked up. The radeon and drm related parts of the syslog are below. If you need further information, feel free to ask.
I have the same problem with the same APU. Disabling power gating (set enable_gfx_power_gating to false in sumo_dpm.c:sumo_dpm_init) fixes it. So this problem may related to power gating.
The difference in power consumption seems to be small, but I'd still prefer it working.
By the way, the "disable_gfx_power_gating_in_uvd" quirk is not actually used, seems to be some leftover from debugging or such.
