I've got field systems running netbsd3 and Xfree86 at the moment with 
DDC disabled and these are likely to be upgraded to netbsd4 and xorg in 
the future. The problem is that some of these systems are using VGA 
cables that lack the line required to probe the monitor, so X won't 
start up with DDC enabled.

Thanks for your reply,
