Hi Igor,

I have a brandless DVB-S tv tuner card also, with a dm1105n chip. I was 
getting the "DM1105: could not attach frontend 195d:1105" message with 
the latest kernel also, but I applied this patch to the dm1105 module 
and now the card's being recognised  (though is still listed as an 
ethernet controller with lspci)

My dmesg output is:

dm1105 0000:01:05.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
DVB: registering new adapter (dm1105)
dm1105 0000:01:05.0: MAC 00:00:00:00:00:00
DVB: registering adapter 0 frontend 0 (SL SI21XX DVB-S)...
Registered IR keymap rc-dm1105-nec
input: DVB on-card IR receiver as 
/devices/pci0000:00/0000:00:1e.0/0000:01:05.0/rc/rc0/input6
rc0: DVB on-card IR receiver as 
/devices/pci0000:00/0000:00:1e.0/0000:01:05.0/rc/rc0

The card is one of these:

Scanning doesn't appear to give me any results.  Should this be working? 
  Anything I can do to test the card out for you?

Cheers,
Matt.
