> Today I decided that it would be nicer to use upstart and udev to decide when to start mythbackend so I wrote a 2 line /etc/udev/rules.d/dvb.rules file to emit a custom "tuner-add" event with a variable "CARD_NO" set to the adapter number:

Actually you don't need to create a custom udev rule. Turns out that 
upstart-udev-bridge generates upstart events from udev events. See these 
web pages:

http://upstart.ubuntu.com/cookbook/#upstart-udev-bridge
http://www.mythtv.org/wiki/Upstart_mythbackend_Configuration

So now I have my /etc/init/mythtv-backend.conf start conditions like this:

start on (local-filesystems
         and net-device-up IFACE=lo
         and dvb-device-added KERNEL=dvb0.frontend0
         and dvb-device-added KERNEL=dvb1.frontend0)
