Same problem for me. A partial solution was to install a vanilla kernel from kernel.org. cx88-alsa loads now (after working around an I2C-related bug) but the audio I get out of it is wildly distorted - mythtv sounds like it is sampling at ~8 kHz but is otherwise clear, kradio has this growling, sort of "industrial" noise on top of the audio from the radio station, etc.
