Ah, not true! :-) At least in the case of the BusLogic cards...
There is a jumper at the top of the card that will enable the card's
floppy controller even if it isn't "configured" yet. Normally, you'd
leave this jumper off and just configure the thing in the EISA config
utility. But if you're in the situation you just described, you can
short that jumper and the floppy controller will work, regardless.
