That's a cryptic answer but, then again, I wasn't really clear with my
questions. I'll try again:

 1. Can we get a pm-is-supported function?

 2. Can you add pm-suspend-hybrid as a command and just stub it out for
    now as well as make "pm-is-supported --suspend-hybrid" return FALSE.
    Then vendors with s2both etc. can patch things in until this goes
    into pm-utils mainline.

    The important thing is to get the interface right - we can worry
    about implementation details at a later date.

 3. When do you expect a release to happen? The lack of pm-utils
    releases is holding up the release of HAL 0.5.9 and frankly it's
    not making me (nor others) happy.

Thanks.
