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' ...

drivers/video/radeonfb.c:845: error: for each function it appears in.)
