Please disregard this message.  I don't know exactly what was causing
the problem, but it was not related to hostap.  For some reason I was
getting that error inserting all modules.  The kernel version had not
been changed although I did at one point run a Debian script 'make-kpkg
modules_install' to create a package for a different module and I think
it screwed something up.  Normally if I need to add another module I can
simply change the config and re-run make and there are no problems, so
this script must have done something.
