I'm running the stock Mythbuntu Kernel 2.6.31.  For the HDPVR I
downloaded V4L trunk from Hg and applied your patch to it.  For lirc I
pulled down the patched bits from your git tree.  If you can't think of
anything else to check I'll try to find a box I can cleanly install on.
If it's not the drivers/patches it could be something about my install.

I also extracted the drivers' source from Fedora and diff'd them against
my source.  Aside from some refactoring I wasn't able to find anything
obvious that's missing.
