The "800x600 but not stretched" issue sounds like it could be related to the 
initial_config bug I fixed this week.  Can you give Dave's latest drm-next 
tree a try?  It fixes that bug (among others).  Also the 2D driver needs a 
few fixes we're still working on.  The intel-gfx at lists.freedesktop.org is a 
good place to watch for those.
