Hi, Martin,
I want to clarify about setup the Graphic memory in BIOS, for OLPC XO-1
platform, XO-1 is set up to 14MB or 16MB (default).
I have been test the Rotate operation in 14MB, if the Graphic memory is
large than 10MB, it can do the Rotate operation, so setup to 16MB or 14MB, it
will normally working.
So the Graphic memory doesn't need to setup to 32MB.
Thanks,
Hunk Cui

I just added a FAQ about this in the driver's README.
