Not exactly the _running_ kernel, but the _target_ kernel.

Because it is useful to be able to compile modules for a target kernel
that may be different than the running kernel, and a symlink is a
good way to point the target of your choice.

I don't see how system headers are related to modules compilation. The
flameable symlink is the /usr/include/linux, but it's a different issue.
It is something that on some other distros points on kernel includes
from kernel sources, but as you said, on Gentoo, we have a linux-headers
package and a real directory, so we do things the right way.


Now, about /usr/src/linux-beta, I don't neither understand its semantics
or usefulness. Obviously, /usr/src/linux is the way to go also for 2.6
kernels, at least that's what is assumed in modules ebuilds, so I
usually just delete linux-beta or ignore it.
