xorg resolution on new laptop

[Mark Moellering]

Michael,

	I am using a SGI-1600SW (1600 x 1024) and I have found that I must specify 
the HorizSync and VertRefresh values in the monitor setting of my xorg.conf  
to get it to work properly, even though all the docs say that it is supported 
using the GLINT R3 driver.  
	Also, I am assuming you are using X 6.9  I have found a large number of 
problems when I tried using X 7.0 on Linux.
