Thanks for all this new work! I'm sorry I haven't been able to be as
responsive as I would like. Hopefully I will be able to spend more time
on this soon.

I see you grabbed the sata link power management script. This script
actually causes some device failures on Ubuntu 10.04 LTS (which is based
on 2.6.32). We are near to releasing a stable release update to remove
that script. I hadn't deleted it yet from our development tree in the
hope that we could fix the kernel issue before 10.10 ships. However, I
think it makes sense to release this script as you have it in pm-utils,
but to disable it by default until we can confirm it is fixed in the
upstream kernel.

I will download and test out the new package. I think overall we'll
probably just stay in sync with your scripts upstream now and get rid of
our own policy package. We may drop the sound HDA powersave
functionality and default to powersave all the time (not just on
battery), but you've written the new script so we can easily disable it
without having to hack around it :).

Do you know when this might be released? I hope we can pick it up for
Ubuntu 10.10, in which case it needs to be released in the next month or
so if at all possible.

Again, thank you so much for the integration and writing of the new
scripts. You've made this task much easier for me, and I think it will
improve performance for Ubuntu users and users of other distros greatly.
