 well, regardless, it's too late.  there will be no further changes
(except one, related to adding a reset line, and that's more than i'm
comfortable with).

 no it does not.  the diode does the job.

 a 3.3v point is not necessary.

 which will not be provided.

 tough.  they can be solved.  "ease" has nothing to do with it.  it's too late.

 the answer's no.  it's too late.  this should have been raised 18-24
months ago.

 there will be no changes.
