Newbie seeking support to install DVICO hybrid tuner card

[avacado]

I realize this is not a support forum as such, I just wondered if
anybody else has bought this card or similar and worked out how to
install it.

CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)

My drivers seem to have diappeared, there is meant to be demux and
frontend files in /dev/dvb/ but the whole dvb directory has
vanished...

dmesg [abridged]

Any ideas?
