fb configuration is done in at least three places, below. The first has 
agp and drm configs. The second configures graphics, and the third 
hardware drivers. What is the right set?

(ps I set drm to get glxgears to perform better.) - Dan

You want radeonfb, which is the kernel framebuffer driver and which has
the code to fix power usage during sleep.

IIRC I had to add radeonfb to my /etc/modules to get it to load on
startup.
