Ok, so after a lot of hair pulling and googling, I finally got my fingerprint sensor to work:

EDIT (03/01/2015): Building the package from source. You might need to set up a build environment first. Make sure that you have packages $sudo apt-get install autoreconf libusb libusb-dev libnss3 libgdk-pixbuf2 git libtool:

Script for auto build and install (written by me and shared from my Dropbox). cd to wherever you downloaded the script to and and run it with superuser:

$ chmod +x install.sh

$ sudo ./install.sh

And voila. Go to user accounts, and you'll see a fingerprint login option.

If you're using ecryptfs (What is this?) for /home, you will encounter this issue at login. Fix.

EDIT (08/10/2014): You can also build your own driver by compiling libfprint patched with 138a:0018 and 138a:0017 drivers (see 03/01/2014). Their licenses apply, obviously.
I don't know for sure, but you can probably build this on a 32-bit system as well.

EDIT (02/10/2014): After switching to Arch Linux, I recently found out that this driver (libfprint-vfs5011-git) is present in AUR. You can download the updated version from AUR for this package (I'll update this answer soon to include instructions as well). EDIT: Added instructions, see 03/01/2014.

EDIT (13/09/2014): After recent updates to fprint, the fingerprint recognition is pretty awesome :P

Pre-built. (See the 03/01/2014 edit for the latest git version):

Open up a terminal (Ctrl+Alt+T) and add the PPA for fprintd.

$ sudo add-apt-repository ppa:fingerprint/fprint

Update your installation.

$ sudo apt-get update && sudo apt-get upgrade

Get the required packages.

$ sudo apt-get install fprintd libpam-fprintd

Download the driver for the fingerprint scanner (shared via my Dropbox). Add a comment if the download is not working. See the latest edit (02/10/2014) for a repository version.

cd to wherever you downloaded the driver to.

Install the driver.

$ sudo dpkg -i fprint-vfs5011_0-1_amd64.deb
