Changes:
18/01/03
MMIO is no longer used, sidestepping cache issues on EPIA-800
TV-Out modes are now better supported - this should be the end
of the magenta stripes :)
Brightness/Contrast controls disabled for the time being - they were
seriously degrading picture quality, especially with TV-Out.
To Do:
Implement Hue/Saturation controls
Support / Test multiple frames
Test colour-key code more extensively
