I have been running with the code for an hour while browsing a number of
picture-heavy websites using Firefox. My laptop definity reacts faster
than before, where I used apmd -C. I have not tried it without A/C
adapter connected yet.
The laptop is a ThinkPad T41, i.e. Pentium M 1.6 GHz. The dmesg from
right after boot is attached. Thank you very much for this addition.
I have been annoyed about apmd's reaction time for a while, and I hope
this addition eventually finds its way into the tree.
