[mythtvnz] Nvidia drivers warning (Gentoo)

[Robert Fisher]

Today, because my nvidia drivers were the masked versions they were updated to 
version 1.0.8756 which then gave me an error in Mythtv - "unable to enable 
video" or something like that.

Going back to the previous version fixed the problem.

/etc/portage/package.keywords now has.....
=media-video/nvidia-glx-1.0.8178-r1
=media-video/nvidia-kernel-1.0.8178-r3

mythtv ~ # emerge -s nvidia-kernel nvidia-glx
