Thanks for the pointer.

I use Radeon so I guess it's an interim update which will get things 
going in the short term followed by hoping someone capable of doing the 
TTM support for it comes forward. Do you have a feel for just how much 
time would be involved in doing the required work to get the radeon 
driver up to scratch? Does your work for the Intel GPUs lay some common 
groundwork which will reduce the work required to update other drivers 
like radeon? (It is clear I have no concept about how all the moving 
parts fit together or what's involved in getting all drivers into shape 
for "the future" i.e. KMS).
