Argh, I knew I forgot something.
The original radeonfb didn't allow mmap()ing any PCI resources, so I=20
added support for that but made it optional to avoid breaking the=20
behaviour the author intended.
So what's missing in GENERIC is
options		RADEONFB_MMAP_BARS
then X should Just Work and radeonfb should restore the video mode when=20=

X exits so the console should be usable again.

sorry for that
Michael
