The end of user-space mode setting?

Parent article: The end of user-space mode setting?

Are we discussing the end of user-space mode setting as a whole, or just for the hardware that has KMS working? I wouldn't care if it were the latter, but as far as I know (which is not much), KMS only exists for Intel, Nvidia and recent Radeons. Are there plans to port all existing drivers to KMS (such as for the Radeon 9200 I use daily or the ATI Rage in my laptop or the S3 Something in a dusty box I still keep just in case)? If so, I suspect the 2-3 years timeframe is slightly optimistic.

KMS is supported on all radeons: stable for r100-r500, staging for r600-r700.

KMS is unusably broken on every Radeon on which I've tried it. It's a nice idea in principle, but to call it "supported" is pushing things a bit if my experiences are anything to go by.

I'm all for removing non-KMS code once KMS is sufficiently stable. It's a *long* way from that right now.

Interesting. It works on my 9250 (old) and my 4870 (new) pretty much
flawlessly: there are 3D artifacts in high-end stuff but 2D and simple 3D
(e.g. oolite, scorched3d, compositing) is perfect.
