dmesg output
You are right - I notice:
[ 3.055513] [drm] Loading BARTS Microcode
[ 3.055579] [drm] Internal thermal controller with fan control
[ 3.061488] [drm] radeon: dpm initialized
This is interesting - as the fan sure works harder under the radeon driver than
the fglrx - and you can feel the extra heat coming out the back of the card.
Is there any further information I can supply re power levels on the card to
try and see what causes the extra power / heat usage?

--- Comment #4 from Steve <netwiz@crc.id.au> ---
I've been digging more into this.... I have 3 x displays - 2 x DVI, 1 x DP.
Looking into debugfs, I can see that the clocks never change from sclk 900MHz,
mclk: 105000.
ie:
# cat /sys/kernel/debug/dri/64/radeon_pm_info
uvd vclk: 0 dclk: 0
power level 2 sclk: 90000 mclk: 105000 vddc: 1175 vddci: 1150
My kernel options are:
# for i in /sys/class/drm/card0/device/power_*; do echo "$i: `cat $i`"; done
/sys/class/drm/card0/device/power_dpm_force_performance_level: auto

Further digging in this BZ seems to show this as a similar problem to:
https://bugzilla.kernel.org/show_bug.cgi?id=60523
/sys/class/drm/card0/device $ cat power_dpm_force_performance_level
auto

-bash: echo: write error: Invalid argument
/sys/class/drm/card0/device $ cat power_dpm_force_performance_level
auto
/sys/class/drm/card0/device $ echo high > power_dpm_force_performance_level
-bash: echo: write error: Invalid argument
/sys/class/drm/card0/device $ echo auto > power_dpm_force_performance_level
