No Console on my Beagle

I've been following the instructions on the web site to build my own kernel. I've gone through the process twice now with the same result: no console login on the serial line. I've looked at the start up log and it seems pretty similar. I immediately thought about the inittab edit that is part of the process but that seems to be fine. Any ideas where to look?

(I'm using a standard Beagle and building under Ubuntu 11.10. The build went pretty smooth.)
