This is absolutely untrue. There is no file conflict or driver name 
conflict for a some time now.

What's the relationship between openchrome DDX driver and kernel ?
Between openchrome DDX driver and libGL ? You're mixing things up, the 
different components are described in the wiki.

It's not because a driver is not in the xorg tree that it's not 
official. Monolithic X is dead, long life modular X. and for what it 
worths, the via driver in xorg is bit-rotting.

If you dare installing it and actually manage to get it to at least 
compile, you're lucky. If you manage to get it to install w/o taking 
appropriate steps to backup the original files, you'll probably break 
your system. And if you actually get it to run, then you're ready to 
pull your hairs out trying to get their forked mplayer and xine to run...
In other words, don't try this at home, kids ;-)

If what you need is hardware acceleration support, you'll never get it 
from unichrome.sf.net driver, even if it was supporting CX700, which it 
will not happen before a long time, if it ever does...

Be sure to know what you are doing before trying anything else than 
trunk, this is not in trunk for a reason. Search the archives for a 
description of what is currently in this branches.
