I thought that you can commit in /include then in /src and then in the supermodule. This way you should have an atomic commit in the supermodule with both changes. But I don't know much about submodules.

Perhaps. Anyway I think there are patches about submodules quite often on the list and it seems a hot topic as there is an entry on the GSoC2009 idea page:

On this page you may also be interested by the "Narrow and Sparse clone support" idea.
