The newer drivers and the open source drivers set a bunch of chroma/luma 
offset flags. The earlier drivers didn't do this.

These settings are programmed using the the binary s3utility, uh utility, at 
the moment however, only the binary "libddmpeg.so" will actually pass these 
values through to the driver though since the code to do this hasn't been 
implemented in the open source driver.... and having never tested that bit 
of code I don't know if it will work anyway!

If you want the code fixed and this does turn out to be your problem I'd 
suggest doing so via the unichrome.sf.net project.
