Is the problem here that there are defvars in the major-mode file being
loaded that depend on one another?  (I'm not sure I understand the
explanation in that bug report.)

If that's the case, then this is inherently fragile, since the user may
have already loaded the .el file otherwise.  So visiting files in a
different order will lead to other results, and eval-ing local variables
before loading the files won't really help, in general.
