OK.. Not sure what GTT is though :)

I've back ported the AGP driver (and vgapci) and I get..

(excuse the spam - I kept adding stuff to it trying to work out why it wasn=

doing anything then realised the new AGP needed vgapci)

I modified config.h to add those #defines and the man Makefile (configure is

OK.
I really only want the 2D driver so DPMS works and the screen saver can
turn the monitor off (although faster 2D would be good as well)
