[dundee] Grub questions

[Nistur]

I was just sitting in the library, waiting for another batch of freshers to
come and I was thinking, is it possible to hide grub entries until a
password is entered? I currently have an md5 password hash in grub.conf and
4 entries, ArchLinux, ArchLinux Single User (locked), Windows XP and one
that reboots the system.
Ideally I'd like to hide the single user entry untill the password is
entered, as it's locked until then anyways. Googling brings up very little.
Anyone know anything about this?

Thanks
