sudo nvram SystemAudioVolume=" "
Seems to use ASCII character values from 32 upwards to represent the different volumes - the default is "{" which is quite loud..
to restore default behaviour :
sudo nvram -d SystemAudioVolume

The MacBook I tried this on however does not seem to do as it should.
After a reboot the value of SystemAudioVolume seems to get set back to 'w'...
Oh well, I'll just keep on using 'StartupSound.prefPane' found here:

well... it works with nvram. No unnecessary programs needed, just make a script, /etc/rc.shutdown.local, which contains just two lines:
----
#!/bin/sh
/usr/sbin/nvram SystemAudioVolume="S"
----
S is ascii(83), A is more silent, a is louder. thanks.
