Hmm, I'm not 100% sure how TwinView works, but I think its similar to 
the MergedFB mode from ATI and also radeon. And those don't provide 
Xinerama capabilities. Instead they let X11 apps think they handle just 
1 large desktop and the driver makes sure the 2 screens "look" into the 
right parts of that large desktop. So maybe its not the number of 
containments, but simply the size of the one you do create...
