These error messages were probably because I didn't seat the card 
properly.

No.  I have built vanilla kernels before but I was avoiding it until I 
have to again.  My test system is using kernel-2.6.17-2mdv which 
knows about cards up to at least 94.  The last line 
of /usr/src/linux/Documentation/video4linux/CARDLIST.saa7134 is; 
"94 -> LifeView FlyDVB-T Hybrid Cardbus         [5168:3306,5168:3502]"
It is a Mandriva beta for 2007.  It is mostly self consistent - and I 
already had it installed.  

How recent a snapshot should I be using?

I can give 87 a whirl as well.

My card has been quite "temperamental" although you can blame me for 
not seating the card properly on at least one occasion.  Strangely 
Philip's card is also being temperamental.  There might be another 
problem as well.
