Split hack_noDepthFrameBuffers on two options:

Browse Source 
hack_noDepthFrameBuffers and hack_blurPauseScreen.

hack_blurPauseScreen is for games, which copy color buffer into depth buffer area,
blur it and use as background image. Examples: Conker BFD, Mickey USA

hack_noDepthFrameBuffers is for games, which never use depth buffer area as texture
Example: F-1 Pole Position, Mario Golf.
