As far as I know, your xorg drivers need to match your kernel, and each
version uses a new kernel, so...
With Feisty, we're using a driver compiled from source and the via
binary, as described at:
Unfortunately, there isn't anything comparable for Gutsy, and the
openchrome, xorg, and unichrome open source drivers gave unacceptable
performance, or at least I ran out of time to find a way to make any of
