Hrrm  I have a SAA 7131E  PCI dvb TV card here...
one of the 'not detected' as dvb card, gives <rant> no eprom error in dmesg  etc...
I have full details, scans of back/front, , about to write out chip-numbers.
I strongly suspect it can work if the correct type added to driver list.
Any idea of best approach?  post links here?  write to a particular list?  driver author person?
