However, you probably don't need radeonfb. X.org should be able to get it going as a secondary just fine, but your text consoles will have to remain on the intel. In the long run (though it might already work with latest upstream), the new radeon KMS should be able to initialize those. Cheers, Ben. > I've tried latest 2.6.27.x and 2.6.30.x kernels.
