It looks to me like the randr_branch was merged in r593, whereas the 
ttm_branch is started from trunk at r528 and synced up to r592. Hence 
still missing the RandR work.

Kernel will be at least 2.6.22 I think. Completely new drm (not released 
yet). Xserver with EXA 2.2, libwsbm.
libwsbm is in principle ready-to-go, but we're discussing some interface 
changes to simplify it a little.
libwsbm is basically a buffer manager abstraction that is intended to 
provide buffer management with- or without drm.

So for now, consider the branch a work-in-progress thing that also is 
used to keep track with latest openchrome development, and for reviews 
and comments.

What's missing at this point is the device initialization code and 
command submission code needed for non-drm operation,
and XvMC fixes. Perhaps rename the ochr_ files to via_ considering 
recent events.
