R500 Fingerprint sensor, Bluetooth, and Volume Control

Coming across this page on an R500 gentoo install gave me some things to try:

First, the command
produces the output
found USB scanner (vendor=0x08ff, product=0x1600 [Fingerprint Sensor]) at libusb:002:003 # Your USB scanner was (probably) detected. It may or may not be supported by # SANE. Try scanimage -L and read the backend's manpage. it should be possible to use.

Second, the bluetooth patch at is required. It was written for 2.6.14 and of course fails on 2.6.22. Manually applying the patch succeeds, but no HCI finds no bluetooth devices..

Third, the xmodmap entries are provided, making the Volume Control fix a no-brainer.

Changes to /.xmodmaprc:
keycode 160 = XF86AudioMute keycode 174 = XF86AudioLowerVolume keycode 176 = XF86AudioRaiseVolume
Changes to ~/.xbindkeysrc :
"amixer -c 0 set PCM 2dB+" XF86AudioRaiseVolume "amixer -c 0 set PCM 2dB-" XF86AudioLowerVolume "amixer -c 0 set PCM 0" XF86AudioMute
