[gentoo-dev] kernel source for gentoo

[Collins Richey]

I'm trying to understand where you hide the kernel source on gentoo and
where the options used to generate the standard gentoo kernel are located. 
All that I find under /usr/src is several sets of /include directories but
no source tree.

The kernel you supply, for example, has no sound modules compiled, and I
would like to recompile for sound support (esssolo1.o and soundcore.o are
needed) without breaking anything else.

I understand building kernels from way back, but what's the gentoo-style
procedure for doing this?

Also what is necessary to get ide-cdrw support.  I notice that /dev/sr0 ...
have not been generated.

TIA
