Something I've always wanted and have thought about writing is a
generic LED driver that basically collects blink events from various
sympathetic drivers and an MD driver that can drive whatever LED
hardware is available on a machine.. Then a userland 'ledctl' that
connects various events to various led's.
Once, a long time ago, someone did a parallel-port based led-bank and
tweaks to 386bsd to make them do stuff... I built one, hooked it up
and started tweaking drivers and found it helpful; especially given
how unstable 386bsd was...
anyway, I've never gotten around to even seriously thinking about it
but I still want it...
