Here is the new radeonfb. It doesn't remove the old one, just in case,
though CONFIG_FB_RADEON now builds the new one.

The new driver supports recent cards, has better monitor detection,
including DDC2, fixes a couple of constants in the old driver, and a lot
more.

I had to add an empty fb_set_suspend() function to fbmem.c (the real
implementation is in James tree and will be here soon).  That means that
Power Management on Apple laptops isn't completely right yet until the
core fbdev fixes get in, but it's good enough for now.
