I mean that there is a physical rfkill switch (actually more like a
toggle button) on the laptop:

Because they are just buttons and not actual switches, they are lights
that should indicate whether or not a radio is on or off. This works
for bluetooth, but not for wireless lan. Without informing the driver
of the LED pin, the wireless lan LED never lights. Its a 100% soft
LED.

So no, the LED does not work with or without the emachines patch. It
only works if I instead set sc->led_pin to 1 and sc->led_on to 1. I
only mention the emachines patch because it tries to cover 100% of
AMBIT systems, whereas my laptop wireless chipset identifies as AMBIT,
but its LED is wired differently.
