fd0 problems

The fdc driver doesn't seem to work as it is supposed to.

beard /home/manlix# mount_msdosfs /dev/fd0 /mnt
beard /home/manlix# ls /mnt/
p4p800.rom
beard /home/manlix# rm /mnt/*
rm: /mnt/p4p800.rom: Input/output error
beard /home/manlix# cd /mnt/
beard /mnt# ls
beard /mnt# cd
beard ~# fdformat fd0
fdformat: open(/dev/fd0): Device busy
beard ~# umount fd0
umount: fd0: statfs: No such file or directory
umount: fd0: unknown file system
beard ~# fdformat fd0

And this appears in /var/log/messages
