Wasn't my first patch series (the one where I always waited
nominal_vblank_period) implementing option 2? If constant wait time is
acceptable, I can go back to the first patch series and simplify it
even further (e.g., forget nominal_vblank_period and just wait for
some fixed hard-coded time). That would address my original objective
(i.e. avoid dissipating extra power when we turn off the screen) and
would be very simple.

If that is not acceptable, and you insist on option 1, then I agree,
my second patch series needs more work.
