F18: when closing the lid, pm/sleep.d hooks not being run

NM should, but it does not yet:

And there are dozens of applications out there that used to utilize the UPower signal and haven't been given proper chance to adjust to the "new approach", so they are broken at the moment.

I don't have any objections to the new suspend framework, it sounds good, but GNOME+systemd developers haven't ensured much continuity. Which is something I see a lot in OSS world, and it doesn't have to be this way. If GNOME developers had ensured the old signals had been sent even with the new suspend framework, at least for one release, we wouldn't have had so many broken applications.
