The systems I see shipping in the next 6 months or so will  be  based
on 2.4 kernel; I think we should define this feature rather sooner or
later to try it out and get it right.

Of course, we can always add this locally, but why not do it now when
we know it needs to get done?

The command line is pretty limited in leght, and there are many  more
"interesting"  things  you want to pass to proprietary drivers etc. I
rather had common stuff like this somewhere else...

If you ask for my opinion: let's do it right NOW, and stick with this
in 2.5, rather than wasting some work  now  for  a  preliminary  ugly
solution  which we think will get thrown avay (which might not happen
as expected), and then spending even more work to do it right.

If you know what  the  final  version  will  look  like,  then  let's
implement this now. And be done with it.
