Er, what stops it from running, if you have it and the hardware driver
built in, and not loaded as a module?  Of course, you won't have an
address configured (at least on some distros), which means that you'll
never get to the TCP or UDP protocol level, but hardware interrupts
will still be delivered to the CPU, which will send them to a hardware
driver, which will do something with them, no?

Indeed. It will deliver them up to the rest of the networking stack in the kernel. And if you want working TCP/IP, just ifconfig the interface up, add a default route to taste, and start using it. You can even resolve hostnames if you can read /etc/resolv.conf. It's all there.
