The original intent was to share Kbuild files between the unmodified
drivers build and the normal Linux one, and the 2.6.18 version of the
driver did just that.  That's not particularly interesting, though,
because I'm not going to submit the 2.6.18 driver and the later
versions' Makefiles can't be used that way.  I guess I should change

Although, now I look, the unmodified drivers don't build for a 2.6.27
kernel even without the NC2 patches applied.  That kind of suggests
that nobody's using them anymore, in which case this patch (as well as
the previous one) should probably be dropped.
