location of kernel modules

[Colin J. Raven]

Can anyone please tell me where the kernel modules are located, and 
where are they described? I ask this so that I can figure out which to 
include/exclude in OPTIONS_OVERRIDE in /whatever/make.conf (separate 
post).

I'd hate to *guess* at what to include/exclude, that sounds sort of 
risky..and I'm assuming there must be some method for doing this for 
someone of my (thus far) hopelessly limited experience.

Regards & TIA,
-Colin
