hi gary --

something sounds wrong here.

to be clear:  when you say "once a machine sleeps", are you
referring to the power light flashing with screen on?  or with
screen off?  the former we've called "suspend" in the past.  the
latter we called "sleep", and it was only available manually (lid
close, or power button).  powerd muddies the waters by entering
this mode automatically after a longer timeout.

by default, the screen should dim at 2 minutes, the laptop should
suspend 10 seconds later (power light starts flashing), and after
a total of 4 minutes, the screen should go off (what we called
sleep mode).

so, assuming you haven't changed the config from the default:

if the screen is still on, either of the above should awaken the
laptop.  if the screen is off, neither should cause wakeup, but nor
should they cause the power light to come on on.

if the screen is on, the power button should bring up the
powerdown graphical "menu".  if the screen is off, the power
button should awaken the display (and pressing it a second
time will bring up the menu).

the amount of time required for the power button to be recognized
should not have changed from any previous release.  that's
controlled by EC firmware.  (and it's always been possible to tap
it so briefly that it doesn't register, but i'd guess that's not
what you're describing.)

yes.  we'd like to avoid that.  :-)

if what you're seeing doesn't fit what i've described (and it doesn't
sound like it does), i guess we have some debugging to do.
