Did you try ivtvctl -a with the device option each for the
corresponding /dev/video devices? I think per default it only checks the
first one...

...the next line looks like the tuner is set to pal (0xff):

From the rest of you dmesg output it really looks fine with detecting properly
both first and second card. Did you explictly tell ivtvctl to set up the
settings for /dev/video0 and seperatly for /dev/video1? Also to tune the card
you need to tell ivtv-tune to talk to the respective devices....
What frequency to use:
When i first wondered what frequency to use i just ran scantv and it detected
the proper channels which are stored to .tv/stations in your home per
default. Maybe use scantv (part of xawtv...) to check whether it can find
some channels. The channel numbers then can be used with ivtv-tune to switch
channels.
