I was skeptical, but after applying this update to my Powerbook G4 1.5 GHz with Bluetooth 1.1, the "Allow bluetooth devices to wake this computer from sleep" option is no longer grayed out and I am able to wake my computer up with my Apple bluetooth keyboard. The keyboard continues to work without problems. Hotsyncing my Palm T4 still works. Tranferring files from a Nokia 6310i and from a Motorola V3 Razr also both still work.
