This is really excellent and very wanted addition to the radeon, a huge 
thanks Alex for giving a second life to my old TimelineX with hybrid 
AMD/Intel graphics. Intel ironlake became a bit outdated already but 
with ATi HD 5650 I was able to drink tee all day long since it never 
came lower than 90 degrees Celsius.   Now it comfortably sits at 55-60 
so I can use it back again.

As I noticed it supports now either dynpm or profile method of clocking, 
however profiles themselves also have several (3) power states. Also 
during init phase it writes that it switching from boot to performance 
profile - so what exactly is the difference between dpm and profile 
method? Will dynpm react to ACPI events like lid closed or AC offline or 
I better to add calls to acpid event handlers to tweak the profiles/methods?

In any case it's just a new breath to my relict brick, especially now 
when its successor is at service repair :)
