Here's a modified version (I called it version 2) of the ToshibaBluetooth driver compiled for Lion (32 & 64 bits).
It's basically the same, but just a few sanity checks were added as well as basic Power Management, also I modified
the info.plist to match TOS6205 device.
The zip file contains the source code as well as the kexts, let me know if it works and/or if any problems arise.
I have a Qosmio X505 running Lion (10.7.1) and works like a charm.
Works perfectly with my Satellite L500-164 running ML 10.8.3.
