I finally got a chance to play with this.  Turns out asus-laptop DOES
work.  It however does NOT work if asus-acpi is already loaded, which
for some reason udev likes to do automatically because both claim to
support the same devices, but they sure aren't equal.

Now once asus-acpi is unloaded and asus-laptop loaded, then it does
appear to do stuff.  fn+f2 does manage to do something, although not
consistently or very reliably, but I suspect that may be a user space
acpi events problem to do with the scripts that are run when the key is
hit, so I have to play with that a bit more.

It does appear that when loaded, the wifi rf_kill is cleared, but after
hitting fn+f2 a few times, it gets set again and never clears after that
other than by unloading and reloading asus-laptop, so something fishy is
still going on.
