patch for using native planar yuv format

Here's a cleaned up version of the patch. Unfortunately, it stubbornly refuses
to run correctly and has even more bugs than the previous version.
Anyway, this should give you an idea what you could expect performance-wise.
However, since it looks like writing to the fb over the pci bus is the limiting
factor, this is unlikely to make much of a difference - bandwidth required will
only drop roughly 25% to your calculated 75mbps (the packed yuv the driver was
using previously needs more space).
