No, I meant that in the way that "if you're running a standard 3.9
kernel already, you can simply take the code from drivers/gpu/drm/via
in the openchrome-drm git and add a few lines to the Makefile" (if
you're *really* lazy and don't have the whole git tree flying around on
your disk already, you can even download the code with "wget -r").

But forget that talking about 3.9, I wasn't aware that the
openchrome-drm kernel in git is in fact a 3.8.0rc6 and not a 3.9rc5.

You're welcome. That almost reads like "Thanks for trying my chocolate
cookies! - *crunch* *mumble* Oh, you're welcome, any more trying I can
help with? *slobber*" :)

I've also attached my dmesg and my Xorg.0.log (from booting up with
via.modeset=1).
