I mean that it should find the disk that contains /dev/hda1 device _node_.

Consider the following:
$ cat > /boot/grub/device.map << EOF
(hd0) /dev/device1
(hd1) /dev/device2
EOF
$ mount /dev/device1 /mnt
$ touch /mnt/file
$ grub-probe -t drive /mnt/file
???
$ ln -s nowhere /mnt/symlink
$ grub-probe -t drive /mnt/symlink
???
$ mkfifo /mnt/fifo
$ grub-probe -t drive /mnt/fifo
???
$ mknod /mnt/device2
$ grub-probe -t drive /mnt/device2
???
Is the same output supposed to be printed in all "???" ? If not, what is in
each one?
