Hi,

This patch adds a new driver to catch RFKill events to the Bluetooth
device on modern Toshiba laptops. Without it, the Bluetooth device is
simply lost on my Portege R500 when the RFKill switch is flipped, and
doesn't come back until after a reboot.

It binds to the TOS6205 ACPI device and doesn't touch any existing
code.

Cheers,
Jes
