I'm running 10.04 with the recent 0.23 auto-builds and I have a dual tuner HVR-2200 card.
This combination has the same on boot race condition where the dual DVB-T tuners are still initialising after the backend has started and the devices are then missing from the available tuners.
Modifying /etc/init/mythtv-backend.conf to contain "and started udev-finish" as suggested above has resolved the problem.
