This doesn't sound right to me.  Wince must pass it back to NetBSD,
because the kernel prints something when I push the power button.  So
why can't NetBSD do whatever it wants then?

I think more likely it's just that NetBSD doesn't (yet) know how to
make the hardware turn off the backlight.  (There's a bit in an include
file that looks promising; someday, I mean to go poking around....)
