Hi Alan,

thanks for digging into the depth of Gentoo! :)

Why not to remove nvidia-settings as a separate package completely and
make the choose whether to install it dependant from the
"tools" flag of the drivers?

I dont think, that there is someone out there, who wants
nvidia-settings /without/ the drivers?!?

Only my 2 EURcents... ;) 

Best regards,
Meino
