Same here, with 4850 mobility.

# echo high > /sys/class/drm/card0/device/power_profile
# cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 500000 kHz
current engine clock: 500000 kHz
default memory clock: 850000 kHz
current memory clock: 850000 kHz
voltage: 1050 mV
PCIE lanes: 16

# echo low > /sys/class/drm/card0/device/power_profile
# cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 500000 kHz
current engine clock: 300000 kHz
default memory clock: 850000 kHz
current memory clock: 250000 kHz
voltage: 1050 mV
PCIE lanes: 16

And the second problem is that the GPU Voltage does not work.
