I suspect there are all sorts of interesting legal issues here. In
particular, the GPL is intended to cover entire works - relicensing
individual source files in a GPLed piece of software in a
non-GPL-compatible way when those files are intended to be combined
with other source files which are still GPLed is a grey area at best.
Since I'm not a lawyer, and I can't afford to hire one, this makes me
want to not touch this code with a bargepole. I suppose I could always
fork the GPL-licensed version, but getting it to compile with new
kernel releases would be a real pain.

(Incidentally, I assume that, since you say that "em2880-dvb and
xc3028-tuner are not derived from v4l code", you rewrote em2880-dvb
from scratch at some point. It certainly looks that way, but I know
that I did have some code in em2880-dvb at one point.)

Basically, I'm left without a working, maintained, legally sound Linux
driver for the hardware I'm using, through no fault of my own (except
perhaps relying on an out-of-tree driver by someone who turns out to
be unable to co-operate with the v4l and dvb developers).

PS. Sorry for the semi-duplicate email; accidentally forgot to send to list.
