There's much diversity here. There's 4 choices at standard addresses, plus
PCI options and a few non-standard choices (though some of those are really
PCI). And people often connect other things to their serial ports, so
blasting all of them may be unwise if you have a 'sealed box' that you then
do a serial install on. Is it possible? Sure. I'm just not sure it's wise.
We tried something similar recently with the GELI boot blocks and it broke
a lot of people.
