All you need is the SystemMenu=false statement as above and two small 
modifications to another file:

The two modifications are:

1. Change line 102 from:
                          <show modes="console"/>
                          <show type="reboot" modes="console"/>

2. Change line 118 from:
                          <show modes="console"/>
                          <show type="halt" modes="console"/>

The lines above both of these should have an item tag refering to the 
appropriate reboot/halt button.  Then restart the gdm.  The shutdown and 
reboot buttons should no longer appear.
