Thanks, Simon, this is exactly what I was asking about.  I will add it for 
the Neographic chipset I have been having trouble with on my old Sony 

Are the two maintainers aware of each other - that is, the xserver-xorg 
one and the kde-guidance?  It would make sense for them to agree on how 
the boards should be configured.  For my desktop computer, KDE got the 
Option and the xorg one missed it.  Those users who either (a) don't use 
KDE or (b) don't ever use KDE to set the video hardware won't get the 
benefit of this.
