It is, but it is only easily possible (that is, without using special XS code) for 5.8.1 and above.

# pass a module name
# returns list or count of coderefs for unrun INITs in the given modul
+e
# empty list/undef if something goes wrong
sub get_inits_for_module {
   use 5.008001;
   use B;
   my $mod = shift;
   eval {
      map $_->object_2svref,
         grep $_->GV->STASH->NAME eq $mod,
            B::init_av->ARRAY
   }
}

Remove the grep line to get unrun INITs for any module.

In general, any module should provide something that can be called to initialize it for circumstances where INIT doesn't get run, so you shouldn't ever have to do this.
