Very old...

Quite a few other components of GNOME have switched to PolicyKit too.

It depends. What error are you getting? Debian does some things
different to upstream, so it's quite likely there might be debian
specific tweaks too.

We've removed all the cpufreq stuff in newer versions. The ondemand
governor is sufficient now that it can be used on AC and on battery,
and there only exist a very few embedded and specialist targets that
ever need to specify performance. I've written loads about this
before, but mjg put it much better. Read
