For now, it should be an exact string. We should (somewhere) list what
defines get added in, and you always build the string in the same manner.
For now, we just do an exact match.

Later on, we can do some more sophisticated matching that realizes that
just because the kernel lists FOO while the LKM doesn't that that's not a
problem. But that we can do later...

Take care,
