I found the following in sensors.conf. Although this is not related to our case, this seems to be the kind of problem we are dealing with
# The following is for the Inside Technologies 786LCD which uses either a

# You will need to load the it87 module as follows to select the correct
# temperature sensor type.
# modprobe it87 temp_type=0x31
# The sensors-detect program reports lm78 and a sis5595 and lists the it87 as
# a misdetect. Don't do the modprobe for the lm78 or sis5595 as suggested.
This looks kind of familar to me. Back in June I had a some of these "found xxx sensor with thisandthat probability" when I ran sensors-detect. But it didn't find the it87 then.
One of the actions I did at that time (beside others) was to remove more and more sensors from the .config and to recopile the kernel. However, at that time I didn't know exactly what to exclude and if that makes a difference at all. So my way was kind of erratic.
Anyway, my experience and experiemces from others as well as the example from above make it quite clear that probing these sensors may be quite tricky. In your case there is the additional problem of the TV cards. Life would probably be easier without them since you could just take a running configuration and use it.
BTW, when talking about TV cards, did you set up your system as a 64-bit system (AMD64) or as a 32-bit system (X86)?
