Hi,

I never did any measurements or other real investigations, but from a
common sense point of view i would say that...

...yes, disabling ports and other components should save power.
Removing unused pcmcia cards should do so as well.
Unloading the wlan driver and maybe unloading the lan driver if not
needed should also do.

Loading a driver or unloading? I think that at least with things like
the parallel port and modem switching them off in the BIOS is the best.
