Good point. Looking at what things like MacOS do, I'd say fbmon provides
a list to radeonfb, which filters it out and creates the "real" list.

I think it's not time to do a full blown fbmon layer now, we need more
experience with it and it's too late in the 2.6 process. I'll probably
just keep fbmon as a pool of "utility" functions and do most from
radeonfb (and aty128fb if I get a chance to port the i2c code) for now.

One thing I'm hesitating to do is to dive into a driver split &
rearchitecture now or not... 

Ben.
