Actually, part of halting is shutting down the network, which does, in
fact turn the link LED off.

Executing

/etc/init.d/S40network stop

also turns the link LED off. Interestingly enough, manually executing:

modprobe -r smc91x

causes the following crash:

Device 'smc91x.0' does not have a release() function, it is broken and
must be fixed.
