Actually I'm an idiot, I downloaded mingetty, compiled it on the
Beagle Board and it works perfectly!
For those interested:
1) Download mingetty to your Beagle Board from
http://sourceforge.net/projects/mingetty
2) Extract the tar file and in the console "cd" into the new mingetty
directory.
3) To install run:
make
su
make install
4) Edit /etc/inittab
5) Comment out this line by putting a '#' in front of it:
1:2345:respawn:/sbin/getty 38400 tty1
6) Add this line and replace "YOUR_USERNAME" with the user you want to
automatically login:
1:2345:respawn:/sbin/mingetty --autologin YOUR_USERNAME tty1
7) Save the file and reboot.
