Ok, it has been released in 2.6.30.1.

Try latest wireless-testing or 2.6.31-rc1; there may already be a fix
for your hardware thanks to recently added rfkill support.

There's the /dev/rfkill device (see http://git.sipsolutions.net/rfkill.git)
and I believe there are files under /sys/ as well which show the state but
I don't have the details handy (/sys/class/rfkill/xxx/state?).

Also I don't have any hardware with a kill switch/LED so YMMV :)
