KMS with Radeon Driver

[jojo_beef]

Now that Christmas has come (http://www.phoronix.com/scan.php?pag...item&px=NjYyMQ), is there any way to test Kernal Mode-Setting?

1. What code does one need, other than the modesetting-gem branch of DRM, to enable KMS?

2. How is KMS enabled? The Intel driver has the i915.modeset=1 kernel boot option; is there a similar switch for Radeon?
