Right now it just does dynamic engine reclocking; all asics are supported. Support for the external thermal and fan chips is not implemented yet, but requires the i2c work in the branch to be possible. The i2c work also allows for the use of external tuners and decoders on AIW cards.
If I understand the code correctly the code only handles PowerPlayInfo tables with a revision <= 4. And according to the atombios disassembler my bios is using revision 5.

KMS works nice here on my new Vapor-X 5770.
Only Multi-Head doesn't work so nice. I can't see the Mouse-Pointer on the second Screen. Apart from that I can use both screens in a normal way. Should I create a Bug-Report about this?
System is a Gentoo Linux, drm-radeon-testing commit 7cb72ef on KDE 4.3.5
My understanding from agd5f was that the dual-screen issues were more with UMS than KMS. I don't remember seeing the mouse pointer issue reported before.
Probably worth giving it a try and reporting bugs if you see them.
