I've done some work on this myself and I've been hacking the kernel for where the issue might be. I was able to get a working version with a 2.6.8 using a vanialla kernel on Warty so I'm comparing what the patch set was back then and compairing everything the alsa and drivers/video/saa7134 modules in each major kernel since then. So far I'm a little baffeled what might be going on here.
