[coreboot] coreboot ThinkPad users

[Patrick Rudolph]

Dear coreboot ThinkPad users,
with the current master (and next stable release) it is possible to
power cycle the BDC (Bluetooth Daughter Card) from within an ACPI
compliant OS.
As the implementation follows the vendors one, all you need is to use
existing drivers, like the thinkpad_acpi kernel module on GNU/Linux.
You can use keyboard shortcuts or toggle it from the desktop
environment's settings dialog.
It should work with all ThinkPads currently supported by coreboot.

Please test it, hack it or give feedback.

Regards,
Patrick
