I've was able to get a hold of an x86 mac and see the same, and have  
corrected the the ppc
guest issues for both hosts, but it also shows colorspace issues.

The old DisplayState could directly set BGR or RBG via the bgr flag,  
but I cannot seem to find
a similar construct in the new DisplayState code. I've assumed it was  
merged into the flags for
DIsplaySurface, but a few hours testing proved that wrong.

CoreGraphics (the OSX native rendering system) purports there is a way  
to do such colorspace
conversions within itself, but a quick google says "no", so I'll  
continue to look.
