As far as I can tell, the configure test for INIT_MM is bogus on 2.6, which has an empty modversions.h. When I asked about detecting the 'exported' state of a kernel symbol, I was told the only way to do so was via a weak reference at runtime.

Yes the test is bogus. I had a reworked version of the test in the second patch (see the v2 patch in the ticket), along with some adjustments in acinclude.m4.

It doesn't rely on a weak reference. If the symbol is not exported, the "AC_TRY_KBUILD26" macro gets a warning during modpost, and any undefined symbol is considered a failure.
