It very much does matter, if the kernel is compiled with any of a
number of debugging options (as is likely for anyone using Arla on
FreeBSD 6 or 7 right now).  It is absolutely essential that nnpfs.ko
and the kernel be compiled with the same opt_global.h.  (<bsd.kmod.mk>
will fake it if one can't be found, but this hack is only correct for
GENERIC kernels.)
