Could you test for rfkill support in kernel 2.6.31-rc2 or a backport of
eeepc-laptop, and alter your patch accordingly? It looks like support is
present via an rfkill device named "eeepc-wwan3g" (but I can't test this),
and that would be the preferred method of handling this: we shouldn't
hard-code it for a particular GSM device, we should only be affecting
built-in hardware, and it looks like all that'll actually be needed is to
report the state.

See http://dev.iksaif.net/projects/acpi4asus/wiki/Backport_module for
backporting instructions.
