2.6.35 Xorg.0.log with radeon.modeset=0

I'm having problems with getting KMS to work with 2.6.35.
I have earlier configuration with 2.6.34 and KMS works as it should. When booting up I get framebuffer console and X starts without errors.

Steps to reproduce:

  1. copy working config from 2.6.34 to 2.6.35
  2. make oldconfig and double check the differing options, none related to drm/radeon
  3. compile kernel, boot it with different configurations
  4. drm does not initialize, framebuffer console does not came up, X can't open dri

6. If I boot with radeon.modeset=0 drm initializes.

I have tried number of kernel configs without any success. Prior to this I consulted #radeon, but it couldn't find any problems with my configuration. Normally I compile things as modules and it works quite well.
AGP-drivers are compiled as modules/in kernel and load before radeon/drm.
I have tried 2.6.35 vanilla, -rc2, -rc4, -rc6, -rc6, -gentoo-r1 . They all fail the same way.

Any ideas how to get KMS working again?
