That will depend on how the video chip gets turned on and how you have
to talk to it.  I'm still coming up to speed on the OLPC hardware but
am I correct that the VSA inits the video device?  If so then it may
need the legacy shadows ranges to work correctly since I bet it acts
like a standard vbios.

Are there schematics up anywhere for reference?
