Well, more that it should mean no more panicing if you set your AGP aperture 
to 256 MB in your BIOS and then start up X11.  I need to verify that I can 
now do this before I MFC this to 6.x.  We are limited to an aperture of 128 
MB at work right now because we run out of KVA when starting X with the 
aperture set to 256.
