Would anyone be interested in a patch to create LED triggers for the new
LED subsystem in the kernel?  Right now, the ipw2200 driver works only
with LEDs attached to the card, but there's a new subsystem in the
kernel for generic LED classes (that display status information) and
triggers (that generate status information).

Separately, I've written a patch that links the LEDs on Asus laptops
into the LED subsystem.  If I wrote a patch for ipw2200 that created LED
triggers for the link and activity lights, then people who have LEDs
that work with the LED subsystem, but aren't attached to the card, can
use them.  Specifically, Asus laptop users could "attach" the ipw2200's
link LED to their wireless LED with a single "echo ipw2200:link >
/sys/class/leds/asus:wireless/trigger" (names of triggers and classes
may change).

I'm not sure how this would get integrated with the existing LED stuff.
Probably it would just create the triggers no matter what, since (unlike
the LED code) they won't cause trouble if they're not used.

Comments are appreciated.

Thanks,

Thomas Tuttle
