I'm beginning to wonder if something is screwed with i2c in 2.6.17 (or has 
changed in some way that DVB isn't updated to cope with yet).... The above 
shows that the budget-av driver _is_ seeing your card, but its not able to 
communicate with the stv0299 frontend over the i2c  bus.

I've seen several other reports of problems like this with 2.6.17 and 
budget-av + budget-ci. As far as I can see there are no patches to DVB (in 
the 2.6.17 vanilla) that would cause this (I may be missing something obvious 
of course).
