No. Waiting for them here as well.
The DRM module is probably the smallest thing, and deeply interwoven
with the X module and the Mesa driver. With the ATI architecture it
might be that we could even work w/o a kernel module and be secure (I
have some ideas for that), but this is pure guesswork w/o register
documentation.

Let's wait and see what type of 3D engine r5xx and r6xx use. Maybe it's
related, maybe it's completely new.

We haven't decided on a memory manager yet. ttm is certainly something
to consider, but I haven't looked much at it (or alternatives) yet.

Whether Gallium is an option or not is also not decided yet. But that
could be changed later on as well. But until some 3D sees the light of
the day, it's probably decided by the community.

My 2 cents
