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. Ben.
