I have a feeling that it stays more on when a subject is in sharp focus (it doesn't blink so often).

Yes, that's the way AF-confirmation works. While the camera can't physically link to push the glass around, the autofocus system can still do its contrast detection thing and tell you when it thinks you're in focus by blinking the lights/beeping at you.
I don't know how your particular combination of lens/adapter/body would work, but try it and see. This will also work with regular non-adapted lenses when they're in manual focus mode.
Precision manual focusing is harder than it used to be because dSLRs are optimized for autofocus, and our matte focus screens don't give us the same focus aids we used to have back in film days (prism, split circles, etc.). So, this is the one big arena of interest for folks using manual focus lenses.
