Not really, I don't know any of those games, I tried installing Enemy Territory, but I couldn't figure out how to play it, I kept getting disconnected from the server. I was playing it at 1024x786 with all kinds of detail set to 'high' and it was pretty smooth. I didn't spot any fps indicator though.
So the only thing confirmed broken is x-video. I only know that from mplayer, the video overlay which is the video output facility. So x-video not working, what does that mean exactly?
For more information on X-Video see: http://en.wikipedia.org/wiki/XVideo
When using mplayer you can always revert to a different video driver such as gl or gl2.
