Actually I'm not sure you should even try to make it work -- isn't the
current single-file scenario just pathological in this respect? I don't
think it makes sense to have multiple features (i.e. `provide' forms) in
a single file (this issue was mentioned before). If you want to compile
the single file version, shouldn't you instead remove all the provides
except `vimpulse' (and reorder the code so it will work, if needed)?

(And I guess you know about the

(provide 'foo)
(require 'foo)

trick mentioned in sec. 15.7 of the Elisp manual.)

Yeah, it was more of an attempt to save you some typing when I already
looked at the output of the compilation...
