A wild, but brilliant and insightful guess!  Yes that's it.  So, if I understand
correctly, since I always strip msdos support out of the kernel, that the msdos
kernel module needs to be loaded dynamically to mount /dev/fd0.  It would seem
that only root is allowed (by default) to load kernel mods, thus the vfsload
error when normal users try to mount /dev/fd0, am I right?  Thank you very much!
