I've been experiencing the same issue on my system (Mythbuntu 10.10, amd64, Happauge HVR-1250). I have successfully installed the linux-image-2.6.36-rc8 kernel from the mainline PPA and can say that my tuner is now working successfully.
Someone more adventurous than I might be able to bisect the sources and determine where the fix was committed and cherry pick it back to the 2.6.35 tree.
