Don't even bother trying to get this device up & running with any
repositories out there right now -- it is not going to work.
I have all the code written for this device already -- it's now just a
matter of firmware. I have the device, too. Once I get it working,
you'll see it in my cx23885 tree. I will not post the patch until I
resolve the firmware issue.

Don't worry about it -- I have all the info that I need for this one.

Hmm... I should have realized that you'd be sending this kind of
output... You'll need my patch in order to enable the right GPIO's to
bring up the tuner / demod ic's ..... Tuner is on bus 1, demod on bus
0. Don't worry about this for now.
Stay tuned for more information. If you dont hear from me within eight
weeks, ping me again.
