I just patched the latest drivers available at http://www.tbsdtv.com/english/Download.html to make it build and work against the 3.0.0 tree.
There is still an issue with the IR stuff, that sometimes isn't able to find the headers required. But the main hardware is working (the TBS5922, the only card I own).
But I'm pretty sure the other stuff will work as well.
If anyone is interested in the patches, just contact me and I'll paste a diff to the original sources.
