An interesting alternative to the serial console thing is baking
in an SSH server into the initramfs. There are small SSH servers
built for that, like Dropbear.
Upside is that you don't need any additional hardware and it's
pretty well integrated into Debian. Downside is that you need
BIOS, the bootloader and initramfs working (with the serial you
at least get a chance to fix the bootloader remotely).

Might be worth a try.
