In hindsight, I believe learning C on my own by porting a driver to
the 2.6 kernel was a tad optimistic..

Sill won't compile, and I haven't got to grips with the changes in the
dvb api from when this was written.

No response yet on the linuxtv list. I'll keep working at the code -
it could be a fun way to learn, and the principle seems quite
straight-forward.
