There was some preliminary work in
http://linuxtv.org/hg/~pascoe/xc-test/ that got DVB-T
working with this card in 2.6.24. Analog TV, composite,
svideo, remote controls, etc didn't work (or at least I was
told they wouldn't work and I never tried them). Is that
what you mean by 'quite broken'? I'm not familiar enough
with the linuxtv codebase to make judgements of what you
mean for myself, but am willing to learn. All I've really
done is applied patches that Chris supplied me.

Done, at least some preliminary (i.e. non-exhaustive)
results. See answer to 3) below.

What revision should I apply this patch to?

Where should I report my findings? On-list or off-list?

Fine by me.
