FreeBSD/axp does not really seem to like mounting a FreeBSD/x86
floppy:

axp33# mount /dev/fd0a /mnt

fatal kernel trap:

    trap entry = 0x2 (memory management fault)
    a0         = 0x80
    a1         = 0x1

        pid = 214, comm = mount

When taking a closer look at dmesg I saw that there was not even a floppy
device configured (GENERIC does not have it. Is the axp not yet capable
of doing floppy interfaces?)
