I set up File Vault 2 in Mac OS X Lion with Pre-Boot Authentication (PBA). In PBA-login my USB-keyboard is working, while using a wrong keyboard layout. I can neither use my magic touchpad nor an USB-mouse in PBA. Thus I can't change the keyboard layout located in the upper right corner. I tried unplugging all USB-devices except keyboard and mouse. Nothing seems to help and the mouse cursor isn't moving.
How can I get magic trackpad or USB-mouse to work in PBA login screen or manually set the used keyboard layout in PBA?
Update: Still no (USB-)mouse or bluetooth trackpad support in File Vault 2 Login Screen. Today I talked to Apple Support for over one hour with no result. Every idea is appreciated.

I got a different USB-mouse working. Magic Trackpad is still not supported. – Chris – 2012-01-20T12:09:05.640
