If the machine is a PXE-compliant device [2], it should have a GUID/ 
UUID [1] available.  This can be exposed by sysutil/hal [3] via the  
smbios.system.uuid field.  The sysutil/hal port, though, requires a  
decent amount of dependencies.  You might want to give the pkg  
install a try first.  (I happened to have a lot of those ports  
installed, so it was not an issue for me.)

# dbus-daemon --system
# hald --verbose=yes
16:39:24.418 [I] hald.c:469: hal 0.5.8
16:39:24.418 [I] hald.c:478: Will daemonize
16:39:24.418 [I] hald.c:479: Becoming a daemon
# hal-get-property --udi /org/freedesktop/Hal/devices/computer --key  
smbios.system.uuid
