CVS is not a distributed VCS, so you can't apply tags.  (Developers
can't apply tags except to the central repo.)   So you have a few

  use the git mirror of the netbsd sources:

  If you need to, do a checkout with -D to fix a particular time.
  for the history of then the build works.   While May wasn't so great,
  typically if you update again and build it will have been fixed.

  export snapshots and put them in some CVS, perhaps even CVS.  Given
  Joerg's git mirror, this option doesn't make much sense.

You can file PRs however you like.  The question is who will spend time
to address them and integrate it, and the easier you make that the
better.  Building your driver against a stripped-down kernel is not a
problem, as none of that should matter.   It would be nice to run your
changes against the entire test suite - see tests(7), even if they
shouldn't be affected - the point is to check for unexpected

If you can put more RAM in the machine, I would suggest doing it, just
to speed things up.  Also if you have a faster machine to build on, that
will make things easier.

Use "cvs add", and "cvs diff -N".

In theory, yes.  In practice, I do this all the time and don't have
trouble except once in a very great while.
