So of the machines you tested that have a floppy controller, 25% are
buggy in the way that Kyle described. That's a pretty compelling
argument against assuming that PNP0700 indicates the presence of a
floppy drive. If you're interested in improving this, perhaps you could
try adding a check for the CMOS bytes that indicate floppy configuration
and make that check conditional on the machine being a PC? That might
fix enough of these cases that we could turn the module loading back on
by default.
