So, assuming .gitmodules is versioned (afaics, it is), it would mean
that after a some unlucky git-pull, where someone changed the upstream
.gitmodules ("linux-2.4" for whatever reason is changed to just
"linux"). And suddenly all such local configuration is useless:

isn't there a typo somewhere around "2.6"?
> URL = http://www.kernel.org/pub/linux-2.6.git
because there is no URL to map from.
why can't I just have _repo_ configuration:
[subproject "kernel/"]
URL = http://www.kernel.org/pub/linux-2.6.git
?
It can be first-time cloned from the upstream, but it stays after
people change it to suit their systems. They can depend on it not to
be broken by upstream.

It is quite long-living to be just initial hint. And will be redundant
after the hint loses all meaning (after some time it _will_ happen,
sites do move around), and is just a strange looking mapping key.
Can I suggest a part of repo configuration to be clonable? So that
there is a something in .git/config.dist, which is _cloned_ with
git-clone. The obviuos thing to put there would be subproject
configuration, and maybe there will be something else in the future
(I'd think of description, which is a separate file now, and as for
now, the only way to get this description is to use gitweb or ssh).
git-ls-remote could be made to show this "remote-accessible"
configuration, in case someone have to update/compare local copy of
this config.
