Soldering a seria port is not an option if you want to do something serious
with it.

Then how would it normally be done? I'm hoping to do this more for the experience than for the final product, if only because there's a chance that the reboot problem is hardware related, and the whole box is fairly useless right now.

That's too small you would need at least 2MB Flash and 8MB RAM.

Could 2MB hold a full kernel? If I can compile in the right USB drivers, I can put the rootfs on a flash drive in the USB port (this is a printserver, so it has one), right?
