This will not even work on all devices that use the Motorola 328 CPU. It
will only work on devices that use the LCD controller that's in the 328.
Because the 328 LCD controller will not drive color LCDs, I think it's a
safe bet to assume that some other LCD controller will drive any color
device.
OS 3.5 has new API in the hardware access layer to allow you to change the
screen address. But it's not really something we support...
