Well I'm not one of the knowledgable ones, as you well know Whytey,
but I have an idea! I reckon the dmesg output shows that the cards are
fine from a kernel point of view as it seems to have detected them.
I'm wondering whether it's a udev issue and that the permissions are
such that MythTV can't see them. I remember having to do some
configuration in udev to get my permissions working. Here's what my 2
DVB-T cards look like:

$ ls -l /dev/dvb/adapter0/
total 0
crw-rw-rw-  1 root mythtv 212, 4 May  7  2005 demux0
crw-rw-rw-  1 root mythtv 212, 5 May  7  2005 dvr0
crw-rw-rw-  1 root mythtv 212, 3 May  7  2005 frontend0
crw-rw-rw-  1 root mythtv 212, 7 May  7  2005 net0
$ ls -l /dev/dvb/adapter1/
total 0
crw-rw-rw-  1 root mythtv 212, 68 Jan 27 17:22 demux0
crw-rw-rw-  1 root mythtv 212, 69 Jan 27 17:22 dvr0
crw-rw-rw-  1 root mythtv 212, 67 Jan 27 17:22 frontend0
crw-rw-rw-  1 root mythtv 212, 71 Jan 27 17:22 net0

And here's my /etc/udev/permissions.d/20-dvb.permissions:
dvb/adapter[0-3]*/*:root:mythtv:0666

BTW - not sure if you're using nvram or not but I also had to change
50-udev.permissions to allow mythtv to use it:
# misc devices
###nvram:root:root:0660
###rtc:root:root:0644
nvram:root:root:0666
rtc:root:root:0666

Hope that helps in some way. Sorry if it's a total red herring!

Good luck,
Phill
