I use the following in an S00dev that gets run near the start
of /etc/inittab:

if [ ! -c /dev/ttyO0   ]; then mknod /dev/ttyO0 c 253 0 ; fi
if [ ! -c /dev/ttyO1   ]; then mknod /dev/ttyO1 c 253 1 ; fi
if [ ! -c /dev/ttyO2   ]; then mknod /dev/ttyO2 c 253 2 ; fi

This seems to work for 3.2.12.  I'm testing 3.2.14 at the moment.  I got
the major/minor numbers by booting a default Buildroot build, I think,
using Busybox 1.19.4 and mdev.

If you want to see how I set up my init scripts and inittab, take a look
at BeagleBox:
http://gitorious.org/beaglebox
http://gitorious.org/beaglebox/beaglebox/trees/master/src/buildroot/skeleton/etc

BeagleBox used to boot into X last year, but I had to layoff for a year
to finish another project, so I'm rebuilding the boot process and just
recently got the rootfs properly booting to a login on ttyO2.  Still
don't have access to the HDMI output (re: tty0) - possibly need to load
the dss2 driver or something.

Hope that helps.
