Ah, radeonfb. Please don't use radeonfb if you want to have any chance in
resuming. Don't use any framebuffer on systems with radeon cards. It will
freeze your machine completely. Actually, any graphics activity (framebuffer
or X or svga access) will freeze it.

Without framebuffer, your machine will come back from sleep, but you won't
get any video. We're currently busy to write code which will help radeon
users (I'm one of them).
