Sounds good to me, that way all the 'work' is done by pm-utils, which
is the logical place IMHO.
Now we don't need the SuspendVideo and friends anymore, I don't think
there ever was a real use case for somebody calling SuspendVideo
without suspending the whole system anyway.

To by-pass the fdi files you mean? Maybe we shouldn't make that to
easy; if we do, people that know how get there system to work might not
have that much incentive to push it to HAL.
Maybe we could provide some documentation/script on how to create
and install an fdi file, with a note asking to send it here.
