TBS 6920 remote

[Tony Houghton <h@realh.co.uk>]

I've got a TBS 6920 PCI-E DVB-S2 card, which explicitly claims Linux
compatibility on the box. It works as a satellite receiver, but I get no
response from the remote control (trying to read /dev/input/event5). I
think this is its entry in /proc/bus/input/devices:

I: Bus=0019 Vendor=0000 Product=0006 Version=0000
N: Name="Video Bus"
P: Phys=LNXVIDEO/video/input0
S: Sysfs=/devices/LNXSYSTM:00/device:00/PNP0A03:00/device:12/LNXVIDEO:00/input/input5
U: Uniq=
H: Handlers=kbd event5 
B: PROP=0
B: EV=3
B: KEY=3e000b00000000 0 0 0

And lspci -v:

03:00.0 Multimedia video controller: Conexant Systems, Inc. CX23885 PCI Video and Audio Decoder (rev 02)

Is there an extra module I need to load to make it work, or is any work
being done on this if it isn't supported yet? Is there anything I can do
to help? I'm an experienced C programmer, but not a kernel hacker.
