v4l2 considered harmfull?

[Guido Schimmels]

I noticed the lack of v4l2 support in
glibc-kernheaders-2.4-8.41.src.rpm

I suppose that is because kernel 2.6 at this point is pretty much an  
afterthought still. Or does the subject line apply?

In the meantime, for my own purposes, is it OK to add videodev2.h
and enable it in videodev.h?

# define HAVE_V4L2 1
# include <linux/videodev2.h>
#else
# undef HAVE_V4L2

Would videodev2.h (from kernel 2.6.1) require any further massaging?

Finally, are there other userland relevant API-additions in the 2.6  
kernel, and missing from glibc-kernheaders?
