How to create custom linux-restricted-modules?

[Chris Cohen]

Hello,

just built a custom kernel. But how do I create linux-restricted-modules 
now? I've seen the posts on ubuntuforums and also read 
https://help.ubuntu.com/community/CustomRestrictedModules. But it 
just "doesn't work"... tons of errors.
So, how does one build a custom kernel without loosing the ability to 
use e.g. nvidia drivers in an easy way?
