OK, serial-8250 is clearly just plain wrong, since the 8250 series UARTs
are ubiquitous across just about every platform.
Floppy is special (in the short bus sense), since it is closely tied to
ISA DMA. Conditionalizing this on ISA DMA makes total sense.
No it doesn't. It depends on the ISA DMA API, not that the machine has
ISA DMA.
I have a platform which has no ISA DMA but uses the floppy driver. Please
don't break it.
OK, even more case in point, then.
