Well, this is way delayed, but the problem is that in recent kernels,
modpost generates a fatal error at build time if a non-GPL module attempts
to access a GPL-only symbol. This is a feature, since it lets you detect a
problem at build time that previously would only become apparent when you
tried to load the module. However, it's annoying for us, because our
reference is weak, and while the kernel's loader handles this correctly,
modpost does not.
