Bug#945618:

[thomasw at fastmail.cn]

I did some more testing on this bug this afternoon because I discovered that powertop can generate an HTML report that I can view after assistive tech is re-enabled. What I found is that for some reason, speech dispatcher is preventing the package from entering low power savings like pc2 through pc10 after this commit. If aI disable Orca speech and then run killall /usr/bin/speech-dispatcher, the low power package states start working again. If I just disable Orca speech, the package states do not work. If I run VLC playing music with speech dispatcher not running, the package states work so it doesn't appear to be an issue caused by all apps playing through pulse.
