A quick test shows that unfortunately theory differs from practice here.
Adding ".gitmodules text" to the built-in gitattributes lets the test
Brad wrote still fail. You have to use ".gitmodules eol=lf" to make it
pass. I stopped digging deeper at this point.

I really like this approach. (And in the long run would like to see a
ini-file aware merge driver being used for the .gitmodules file too,
which would just merge submodules added in different branches instead
of producing a conflict)
