Looking at the files, it seems that dv1394.h is derived from a linux
kernel header, which is GPLed... This is probably why dv1394.h is marked
as GPL. If this understanding is correct, I think it cannot be changed
to LGPL, and the correct solution would be to disable dv1394 if
--enable-gpl is not used.

BTW, last time that I tried dv1394 did not work with 2.6 kernels (it was
a long time ago, so the situation might have been changed in the
meanwhile)...
If I remember well, the problem was that a header file (probably it was
dv1394.h) contained some #defines from the 2.4 kernel, which changed in
2.6.

So, unless someone already fixed the problem dv1394 will need some work
anyway...
