Does it? The current state makes power seqs automatically selected by drivers 
that need it, and they do not appear in the configuration menu. If we add a 
description they will then become a visible item, so the logic would be to 
make it user-selectable.

If that approach is preferred, I will also have to change pwm-backlight so 
that it compiles without power sequences. Not that I mind, but I liked the 
idea of not adding yet-another-option to the config menu.

Fixed the code according to all your other comments, thanks!

Alex.
