Hmm, so you'll keep Balaji's work in andy-tracking until it comes
back via upstream ? That may take a while, during which we'll have
different power management in the two trees ...

By the way, regarding screen blanking: the bug that made the
backlight not quite turn off also showed that there's more going
on: it seems that we also don't turn off the LCM controller and all
the Glamo clocks. (Either would cause the LCM content to decay,
which it didn't do.)

So I if someone feels inclined to squeeze out a few more milliamps,
a useful test would be to comment out the action in all but one of
the relevant suspend functions, and see if the remaining one has
the desired effect. Iterate through all of them.
