On my system, vbetool dpms on/off seems to have no affect on the DPMS 
state (though currently I'm remote so the only way I can confirm is via 
xset q).  I *do* know, however, that xset, on my system, does in fact 
change the DPMS state (which allows the monitor to sleep or not), and it 
correctly reports whether the monitor is on or off.
