Correction, (specific to BCM5720) you'd see:
pciN: <unknown card> (vendor=3D0x14e4, dev=3D0x165f) at X.Y
Which, btw, you can confirm to yourself by executing the following within 8=
.3-R (with attached bge(4)):
$ pciconf -lv | awk '/^bge/{print $1,$4}'
bge0@pciN:A:B:C: chip=3D0x165f14e4
Otherwise, you can see an unknown (non-working bge(4)) Broadcom BCM5720 har=
dware by executing (on 8.0-R for example):
$ grep unk /var/run/dmesg.boot | grep 0x14e4
pciN: <unknown card> (vendor=3D0x14e4, dev=3D0x165f) at X.Y
NOTE: On a system where all hardware is probed/attached, "grep unk /var/run=
/dmesg.boot" should not produce any results. In this case, pciconf is your =
tool for probing vendor/device IDs.
