I will need to find whatever register corresponds to GPIO03 and set just that particular HIGH bit?
Yes. Look at the data sheet and maybe as a help you can step through superiotool as well.
(Other keywords in their email were things like "GPIO:0x2" and GPIO:0x18", but I haven't been able to get any additional clarification from them...)
Superios are easier to program than many other components, and are well documented, so you shouldn't have too much trouble. GPIO 3 is what you need to know about how the hardware is built.
