  Well, it's as finished as much as I could do.  It seems to work
for everything I've tried.

  /dev/fd0a is minor device 0, which is AmigaDOS track format.
  /dev/fd0b is minor device 1, which is MSDOS track format.

  If you are using the generic root device, and don't specify -b on
the boot, NetBSD is going to look for a root device.  It searches
/dev/fd?a, /dev/sd?a/, and /dev/cd?a (doing the unit numbers in
reverse order) until it finds a valid filesystem.

  Since the floppy is searched first, the driver is going to try to
read the 'a' partition of the floppy.  If the floppy has an MSDOS
disk in it, the driver will get "corrupt track" errors trying to read
using the AmigaDOS track format.

  I haven't seen the system hang when booting at that point, but I
normally boot with -b.

  If you configure your kernel to explicitly specify the root and
swap devices, it shouldn't search the floppy drives for a root
filesystem.

  The floppy density is reported by the device ID sent by the drive.
If the drive sends the DD identification, NetBSD will report the drive
as DD.  The floppy drive in my A4000 only reports the HD identification
if an HD floppy is in the drive.  I do not know of any other way to
identify the drive as HD.
