******** I fixed the problem. My xorg file had "nv" as the driver in it NOT "nvidia". I changed this and now the 3D rendering is working again:
spc1-burn4-0-0-cust452:/home/mikef# glxinfo |grep rendering
direct rendering: Yes

Its resolution is 1360 x 768 as far as I can tell but if you put exactly this in the xorg.conf file you get a flickering somewhat miserable screen.

************************* Forget this - I have fixed the nvidia card problem*****
BUT ----- I still have the problem with the monitor display not being ideal here.
