It doesn't work, a message box: "umount: unmount of /media/usbdisk
failed: Operation not permitted"

# cat /media/.hal-mtab
/dev/ntfs/usbdisk	1001	0	ntfs-3g
nosuid,umask=007,dmask=002,fmask=117	/media/usbdisk

# cat /tmp/.fuse-mnts

gnome-mount 0.8

not in /media/.hal-mtab so it is not mounted by HAL

I think unmounting from HAL needs parse /media/.hal-mtab file.
