There is no easy way to do this with CVSup, AFAIK.  Even if you do
manage to get only 3-4 files out of a specific CVSup collection, how
will you verify that you have *all* the necessary updates to *all* the
affected files?

You can probably hack a local CURRENT kernel, to merge only the ath(4)
updates if you keep a local CVS mirror of src/ around, but this is very
likely to be a lot of work.  You would have to be careful to watch out
for any updates to other parts of the kernel too, on which ath(4) may
depend.  You will, effectively, have to keep a local src/sys branch.

This is not impossible, and it's precisely what FreeBSD kernel
developers do every day.  I'm just saying that you should know what you
are going to be into, if you go down that path :)
