And, there is a suitable prototype of i82077 FDC device, in
arch/sparc/dev/fd.c.  The project might be started
'cp arch/sparc/dev/fd.c arch/pmax/dev', but, that would be the *12th*
iteration of duplicated FDC implementations.  You feel free to implement
'really universal' FDC good all across NetBSD ports.
