include/linux/module.h was changed in the 2.3 kernels to define
__module_kernel_version and __module_using_checksums as static.
Without that change you get multiple definitions of the variables when
you link multiple objects into a single module.  In 2.2 you have to
#define __NO_VERSION__ before including module.h in all of the module
objects except one.  Search 2.2 drivers for __NO_VERSION__ to see
examples of this.
