You didn't reply about running X or not. Can you try in pure console
without X beeing ever started ? Also, which radeonfb driver did you
use ? My 2.6 tree contains actually 2 of them. (Make sure you are
using my tree btw, mainstream 2.6 doesn't contain up to date sleep
support yet).

Regarding the specs... well... we had _some_ from MkLinux or earlier
Darwin sources (though Apple quickly un-opensourced the PMU driver),
from the Open Firmware forth code, and for things related to sleep,
a whole bunch of reverse engineering & trial & error...

For the code putting the radeon chips to sleep & waking them up, you
have to thank ATI for providing it.
