I believe you'll need to:
a) have a kernel compiled for serial-console support
(the default debian 2.2 kernel lacks this feature afaik), and
b) in the firmware, do "setenv cmdappend console=ttyS0,115200"
or similar to actually redirect the system console.
You should get all the kernel boot messages, panics, etc., over the
serial console this way.
