Soft NAK.

Please have a look at rfkill in wireless-testing (it is going in with the
merge of the net tree, so it will be in mainline really soon).  rfkill has
seen some changes, and no little ammount of that work was to make platform
drivers like thinkpad-acpi and toshiba-acpi work better with rfkill.  The
documentation in Documentation/rfkill.txt was expanded and improved as well,
and will help you get a better picture of how it should work.  The rfkill
changes should also be available in wireless-compat, and they are
backport-friendly.

Please consider updating your patch to the new style rfkill class.  A quick
look at your patch shows that it would benefit from the new
RFKILL_STATE_HARD_BLOCKED, and maybe to some rework to separate the
bluetooth rfkill controller and the input device switch better.  Depending
on the existence of ACPI GPE events when the switch changes state on
Toshibas, you may even be able to get rid of some of the polling...

If you rework/repost your patch, please CC Ivo (the rfkill maintainer) and
the linux-wireless mailing list.  If you want me to try to help review the
patch as well, please also add me to the CC.
