Hm.. It seems like a detection problem.
I just set/hacked the flags in isa/fd.c function fd_probe to FDT_144M;


>>>isa/fd.c
printf("fd_probe entered\n");
        =20
        fdsu =3D *(int *)device_get_ivars(dev); /* xxx cheat a bit... */
        fd =3D device_get_softc(dev);
        fdc =3D device_get_softc(device_get_parent(dev));
        flags =3D device_get_flags(dev);
flags =3D FDT_144M;      =20

printf("flags: %d\n",flags);   =20
       =20
        bzero(fd, sizeof *fd);
        fd->dev =3D dev;
        fd->fdc =3D fdc;
<<<isa/fd.c


the floppy gets detected then, and I'm able to use it.

Normally device_get_flags(dev) returned with 0 (FDT_NONE).
