Just to follow up on this:

I've been using 0.1.2 + no-surfaces-kms.patch only and things have been 
100% stable for me with my "typical" workload.  My environment is:

F20 guest, F20 host, F20 client.

The no-surfaces-kms.patch is attached for convenience of anyone 
reviewing this. After a little sleuthing (which shouldn't be necessary, 
the patch or the spec could mention the bug# that it is fixing), it 
seems this patch addresses:

RH bug#1027831 - kernel BUG at drivers/gpu/drm/ttm/ttm_bo.c:173!
