Hi,

Looks like we are missing something on NetBSD/i386 when running it
on amd64 processors:

* amd_cpu_cacheinfo and amd_family6_probe are not being called in identcpu:

                /* Family > 6 */
                {
                        CPUCLASS_686,
                        {
                                0, 0, 0, 0, 0, 0, 0, 0,
                                0, 0, 0, 0, 0, 0, 0, 0,
                                "Unknown K7 (Athlon)"   /* Default */
                        },
                        NULL,
                        NULL,
                        NULL,
                } }

Is there any reason for this? even there's a PR from gmgarry@ suggesting to
enable them:

IMHO it's very important.
