No, it doesn't.  I've tried adding a CRT monitor through the video-out 
connector and the output is quite acceptable considering that it's an 
ancient monitor.

I never really explored the function keys, but Fn+F6 switches the LCD 
screen off while continuing to display the external one.  It switches 
back OK, too.

It looks as though that is a very specific solution, though, for a 
"i855GM based laptop".  The problem is that having ascertained that it 
is OK with an external monitor I don't see what else I can do.  I'd 
hate to get there next meeting and find the same problem again.  My 5 
minutes next time is something that would be difficult to do without 
it.
