Don't fret, you seem to have found someone who knows what you're talking about 
-- or pretends to.

I'm CC:ing hardware-devel, KDE's list for hardware-related development (nomen 
est omen).

Pretty cool feature, indeed. I've been using something similar when I was more 
involved with the Suspend2 project. I suppose openSUSE ships this?

From a UI point of view, it probably makes most sense to replace the suspend 
option with it, as it's still essentially s3 (but with an extra safety net). I 
don't think another option in the UI there really makes sense, one shutdown 
and three modes of suspend sound like overkill in my books.

In order to integrate it nicely (if you don't just want to replace HAL's 
suspend method), you'd have to add it to HAL (*1), to Solid and then make it 
available in the UIs (shutdown dialog, kickoff, battery widget).

*1 In HAL you'll likely not get it easily upstreamed, but as KDE doesn't use 
upower yet (but planning to), HAL is you current best guess.

I'm afraid just pulling packages won't help you much. You'll have to get your 
coding hands dirty.
