Hello, with the last git kernel 2.6.35.15. With the last packages (xorg, drivers, libdrm, ...). I'm under gentoo. My graphic card not work: Dmesg: http://pastebin.com/EVTap9nF Config's part: http://pastebin.com/KNri9C0w Config's part: http://pastebin.com/Xsp7aD4M DDX drivers seam work for 2D and detect the correct resolution. Thanks to support my card.

it's good? With old kernel it's try well too switch to kms, not with this kernel.
Ok, for some reason the kernel is not able to access the vbios rom while the the ums driver is able to. Did kms used to work on your card? If so, which kernel?
I have try 2.6.34 branch, and this kernel what I try is the kernel 2.6.35-git14 (gentoo) on core2duo linux x86_64
Other behavior, for have 3D acceleration I need activate in the kernel: Device Drivers -> Graphics support -> VGA Arbritration Device Drivers -> Graphics support -> Laptop Hybrid Graphics - GPU switching support And disable: Device Drivers -> Graphics support -> DRM -> kms for radeon
