Fun :-).

Require lpattern in all zones to be same and active before actually
enabling the pattern?

Decide lpattern is not suitable for this and figure out what to with
multi-LED triggers? Someone wanted them for "meters" (CPU load 25% 50%
75% 100% LED bar)...

Skip this hardware feature for now. We don't have to support
everything?
