[Xorg-driver-geode] Geode LX video testing results

[Brunner, Brian T.]

Hello

I did not subscribe to this list, but got "auto-subscribed".
I am not pleased at the presumption.
I attempted to unsubscribe, but no success.

Somebody else gets to unsubscribe me, as I will auto-respond to this

(auto-subscribe isn't rude?  Neither is auto-respond)
