--- Comment #4 from graham <grhm.perry at gmail.com> ---
The code on line 510 of r600.c suggests that there is expected to be two power
states for both POWER_STATE_TYPE_BATTERY and POWER_STATE_TYPE_PERFORMANCE,
presumably one for single-head and one for multi-head. Changing the number to 0
(the first instance of the each power state) fixes the bug and allows low power
mode. 

Could it be that there is actually only one power state for the HD6000? And the
function radeon_pm_get_type_index in radeon_pm.c is failing to find the power
state at index 1, and so is returning the default, high power state?

Also, where would I find the list of power states found in radeon_atombios.c?
