Would taking the suggested commands from PowerTop and adding them to your /etc/rc.local script be a good solution for you? This would save profiling your computer each time as the commands would be run immediately without running PowerTop. If you find a suggestion that doesn't work well with your computer then you wouldn't include it in /etc/rc.local
A power saving feature that can be annoying is to set the audio module to powersave, as it makes an annoying "click" just before a sound is played; however this might be acceptable when running on battery. Therefore perhaps a better solution would be to have an interface with suggestions for saving power that has the options: Use/Try now Use always Use when on battery *Use Always* and *Use when on battery* would be scripted so that they happen automatically without PowerTop being run.
