Tom,

Attached is another patch,  this will break the support for your card, but proves that the 
cx25840 module is required for the DVB-T side of this card.  So before applying the patch make 
sure you have a copy of the working patch handy (or even two copies of the source tree).

Follow the same steps I had for the v0.1 patch, but use the attached (v0.2) patch.  The symptons will be the same as the original patch, i.e. no errors in dmesg, but unable to scam/tune.

Also can you please look at the other IC's on the board and see if you identify them for me.  
I'm looking for an eeprom or similiar IC, as I will need to distinguish between the various 
different boards.  Also if you can get a dump of what is on the eeprom and provide it (or put it 
on the wiki page, or both).  I'm not sure how to do this safely yet, so if you have time google 
is your friend (i2cdump might to the trick).

Thanks,
Stephen
