The gentoo wiki has a section on unichrome, I am not sure how up to date this info is, but here is what it says:

http://gentoo-wiki.com/Unichrome

"This Howto is about installing a kernel and Xorg on a motherboard with
VIA CLE266 or KM400/KN400 chipset. Support for K8M800 and PM800/CN400 is
still limited.

The CLE266 VIA chipsets allow hardware mpeg2 decoding of videos, thus
taking the load off the CPU. At the end of this howto you should be able
to play a mpeg2 file with as little as 5% CPU usage. Multiple mpeg2
steams are not supported by the hardware, so you will only get hardware
decoding for one video file.

The CN400 supports mpeg2 and mpeg4 decoding, but the drivers are still
in heavy development to make use of the this hardware. The next version
of xorg-x11 (6.9 / 7.0) should contain full support for the CL266 and,
at least, partial support for the CN400 chipsets.

A user on the forums has had some success getting the unichrome drivers
to work without using any CVS repositories and without using software
packages outside of portage. It might be advisable to view that series
of posts [1] in addition to reading this HOWTO. "
