At first glance, it looks like the iwi equivalent is dev.iwi.0.radio,
where 1 is on and 0 is off.  It won't let me set it to 0, though,
claiming it's a read-only sysctl setting.

. . . and trying to set the debug.iwi sysctl setting to 1 caused the
computer to reboot (not intended behavior, I'm sure).  Bah.  I wonder if
there's something wrong with my driver.
