+1 for serial console.
I found this useful when I had my NSLU2/Slug and SheevaPlug and had to
disagnose bootloader issues etc. I used a tool called minicom to make
the connection.
You might also want to enable some of the boot logs which I think are
disabled by default in Debian.
You can buy PCI serial port cards if your hardware has none.
