I have what seems to be the same problem with an HD5570 card. Running under the
default profile, the card runs at roughly 60 degrees all the time. The good
news is this does not seem to increase under load; the bad news is that it does
seem to already be hot enough to introduce some instability. I've had random
system freezes and reboots since installing it.

I'm using 2.6.36, radeon driver with KMS enabled. Setting the power profile to
"mid" instead of default lowered the temperature of the card at idle to around
48 degrees and appears to have alleviated the system instability.

It seems that the current default setup is somehow running the card full-tilt
all the time.

I am interested in the dynpm but I wasn't sure about its maturity level.
