Nvidia support

[brad allison]

[jackal@isis jackal]$ uname --release
2.4.19-pre8-ben0

[jackal@isis jackal]$ grep -i nv /etc/X11/XF86Config-4
        Driver "nv"

The XF86Config-4 was created with Xconfigurator (I just changed the Driver 
to "nv").

Then I typed X on the console and the box completely locked.
