I have been looking at the patch - and in as much as it has been posted
quite a long time ago, I was wondering if it had been "merged" with the
present src ?
If that is not the case - then I have to admit the following; I have
never before 'added a patch'. So I would need to know how I do that
(feel very silly and novice like, asking this) ...

I've tried a similar stripped-down kernel approach and it doesn't seem
to make a whole lot of a difference (removed everything which I deemed
safe and rebooted + kldloaded various modules):-/
But it would probably be interesting to know if there are any
significant differences between 6.0 Release, Stable and Current ?
