How much of this is handled in AMD's binary VSA module?  I have been 
looking through both the AMD and OpenVSA source and it looks as if the 
lxvg module is supposed to handle VGA SMIs but I cannot find where this 
is actually done.

Incidentally, I have noticed that the AMD VSA source available from 
dev.laptop.org cannot be used to build an image with CS5536 support.  Is 
this an old version and, if so, is newer source available?
