Correct behaviour of modversion handling has always been a problem. It
works perfectly on RedHat 5.1 if you run a 2.1 kernel (sparc) compiled
with version support.

It also works on a Slackware system (with libc5 and 2.0 kernel).

If you have a solution that is guaranteed to work on _all_
configurations, you are welcome to send us a patch.

linux/module.h does not include linux/modversions.h is MODVERSIONS is
set. I suspect that there is a reason for this.
