This is also obviously broken (and really sad), but actually ends up being
better than what get_kernel_version apparently does, by at least adding
the requirement that the string "Linux version" be slightly more correct.

However, it's also TOTALLY BROKEN.

For example, if the Linux version string happens to be preceded by a byte
that is a valid ASCII character, the grep will fail miserably. So that PoS
is actually going to fail for various random kernels too, and depends
intimately on just what variable _happened_ to be linked just before the
version string.

The fact is, doing strings on the kernel is just not a viable alternative
to real versioning.
