It's working fine for me on a stock 7.10 ubuntu install.

/dev/video doesn't work, it's not supported.

You should aim to use the dvb-apps tools (tzap, scan) and mplayer as 
example tools, or MythTV as an app.

This looks bad, it looks like i2c is broken badly, so that the eeprom 
isn't detected and the demodulator isn't found during attach. This is 
the reason why your missing /dev/dvb/adapterX/

No idea why. Try loading the cx23885 with debug=5 and report any log 
messages here - on this mailing list.
