Isn't this (determing wether or not to load floppy.ko) done (on PC's) by
checking if the BIOS has a floppy configured?
Andrew, can you see if your BIOS thinks you have a floppy (the default) and if
so tell it it hasn't, then floppy.ko shouldn't get loaded anymore and that
should results in a couple of secs ood speedup.
