The serial interface gives you access to the u-boot bootloader. I lose the ability to input anything after the kernel boots, so I can't login to the terminal; that might just be a problem with my device though.
Now, to find that elusive JTAG...

This really good news: we can check out new kernels or booting from the SD card if the bootloader allows this (and recover bricked device when JTAG comes out
) . I'll give it a try.
The serial line becoming unresponsive after boot sounds to me likely because of a different speed setting: it should be 115200 for the login prompt.
