So what is wrong with the current floppy driver (other than being 120k
of code apparently)?

As for floppies that should work, well I imagine on x86 that would have
to be 360k and 1200k 5-1/4", and 720k, 1200k and 1440k 3-1/2". Would
perhaps be nice to still support 160, 180 and 320k on the 5-1/4" drive
too just in case anyone ever wants to read one. Of course some people
might also want support for the higher capacity formats on the 1440k
drive. 2880k would perhaps be nice too for those few people that have
one (I have only ever seen them on decstations, where I haven't seen any
driver ever), and I think a few IBMs. I have never seen a 2880k disk.

In non x86 land, I would think there is a seperate floppy driver given
the odd formats of some of those systems.
