I am in the final throws of building a prototype device for a show.
Unexpectedly I have run into a couple of problems with V4l/bttv/i2c that I
cannot seem to resolve. Briefly here are some facts...

On a desktop system using the defaults provided by the RedHat distribution
7.1 my stuff works. My stuff captures a frame, compresses it and sends it a
live video feed over 100baseT.

Next I put it on an embedded platform. I copied the kernel sources from the
RedHat distribution onto the embedded system and made a kernel. The embedded
system does not have a video adapter or keyboard. The console is a serial
port. While I have tried a lot of variations with varying results, including
hard hangs, however the basic configuration always returns a /dev/video0 -
no such device when an open is attempted. This code works on the desktop
system with the same frame-grabber.

On boot, kudzu finds the frame grabber, Brooktree 847, and configures it.
The actual brand is unknown, there are no markings.

I feel I am very close, and would like to converse with someone to help me
get by this problem. I'll gladly offer some remuneration for the help.

Mike
