Roland,

   I tested with MergedFB and it works perfectly.  Nice speed boost! 
I must note however, that with pageflipping, the crtc offsets still
don't seem to propagate down to the drm.  both crtcs end up at zero. 
that's the same problem I had when I attempted to fix this last week. 
I don't know why.  Other than that, very nice!
