Prepare a USB drive for your teachers to disable the sound:

Yes, it is the same across XO-1, XO-1.5, XO-1.75 and XO-4.

You can also hold a volume key down after turning the laptop on, and
it will repeat.  You can use this on any random XO you pick up to
avoid the startup sound almost entirely.

Yes, during OLPC conference calls and team meetings having some
participant reboot an XO repeatedly was very distracting.  ;-)

Sick of U2?  You can now change the startup sound.
