Currently is reads (as you also have below) "Enable LED support in
iwlagn and iwl3945 drivers". This seems clear to me.

This makes sense.

Some users find the LED annoying and like to have a way to disable it.

This is reasonable.

I do not think this says more than what we already have. I actually
think noting something about a particular platform will increase
confusion (as in "so where is the option if I have an acer laptop?")
because this option is needed to get LED support on all platforms. I do
think what is currently written is sufficient, but if you insist on
having some text there I think it should be simpler. Something like
"Select this if you want LED support."
