You are right. This is what I found.

On the gentoo forum:
Hence the two separate sets of header files:

1. system headers in /usr/include, to build software, and
2. current kernel headers in /usr/src/linux, to build the kernel.

Some e-mail message from Linus on this:
http://www.linuxmafia.com/faq/Kernel/usr-src-linux-symlink.html

And the clearest explaination
http://linuxfromscratch.org/pipermail/faq/2004-July/000159.html
Note the FAQ at the end of this page:

I think on gentoo the so called linux-headers are actually the mentioned 
linux-libc-headers. And on your system the headers are the true kernel 
headers.
The best solution for us right now would be extract what we need from 
the kernel headers and put it in our own header. And keep track of 
changes in the kernel on this in the future. Sad but true.

Give me a little time to get it done :-)
