[Sussex] Gentoo & nvidia-kernel

[David Chapman]

Just tried to emerge nvidia-kernel nvidia-glx
Now when I try insmod nvidia I get

Hint: You are trying to load a module without a GPL compatible license
      and it has unresolved symbols.  Contact the module supplier for
      assistance, only they can help you.

Any help on this ?
It might help to know that I have compiled my own kernel
