With all due respect, per-driver versioning in mainline may be
meaningless (and as you note, modinfo already carries the kernel
version in it), but as soon as it hits a vendor kernel, it means very
much, and is the primary method of denoting to a larger (and mostly
non-driver-developer) audience what hardware is supported, and what
critical (to the vendor) bugs have been addressed.

And some tools, such as DKMS, make explicit use of the MODULE_VERSION
tag to automate updating individual drivers without necessarily changing out the
whole vendor kernel.  Once the vendor kernel "catches up" with the
equivalent driver, DKMS won't replace it any more.  All of the drivers
critical to Dell are separately versioned exactly for this reason, and
those tags are in the code submitted to mainline.  (3c59x isn't in
that category I admit).

Thanks,
Matt
