Replying to self so that it might belp others:

* the CONCURRENCY_LEVEL variable is indeed specific to make-kpkg: if 
you're not using that, it won't help

* to influence the debian/rules file, the proper way is to set 
DEB_BUILD_OPTIONS, like so: DEB_BUILD_OPTIONS=parallel=4 fakeroot 
debian/rules clean binary


Incidentally, I like this second method best because it is not 
kernel-specific: it works with any package which supports this variable.
