Hmmhh I remember I also had problems with sleep in a certain kernel config. but I don't remember the settings... However as the new radeonfb is still pretty slow _here_ I wonder how difficult it would be to fix the compile errors with the old driver, such that I can try reproducing this 'sluggishness behaviour' ...
