Yes, I can login, sudo, and unlock with thinkfinger.  To perform the
latter (gdm unlock) requires a udev rule:

#
# udev rules file for the thinkfinger fingerprint scanner
# 
# Taken from: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/138957

# uinput device
KERNEL=="uinput", MODE="0660", GROUP="plugdev"

Another udev rule that I use sets the power to auto, which is documented
to help keep the reader from getting hot:

ACTION!="add", GOTO="fingerprint_end"
SYSFS{idVendor}=="0483", SYSFS{idProduct}=="2016", RUN+="/bin/sh -c 'echo auto > /sys/$devpath/power/level'"
LABEL="fingerprint_end"

After copying my udev rules:

  $ sudo apt-get install libpam-thinkfinger thinkfinger-tools
  $ sudo /usr/lib/pam-thinkfinger/pam-thinkfinger-enable
  $ tf-tool --acquire
  $ tf-tool --verify (to check)
  $ sudo reboot

Nothing fancy.
