It has been tested:
# snmpwalk -v 1 -c pub localhost:161 | grep Speed
IF-MIB::ifSpeed.1 = Gauge32: 1000000000
IF-MIB::ifSpeed.2 = Gauge32: 1000000000
IF-MIB::ifSpeed.3 = Gauge32: 0
IF-MIB::ifSpeed.4 = Gauge32: 0
IF-MIB::ifHighSpeed.1 = Gauge32: 1000
IF-MIB::ifHighSpeed.2 = Gauge32: 1000
IF-MIB::ifHighSpeed.3 = Gauge32: 0
IF-MIB::ifHighSpeed.4 = Gauge32: 0

And adapters are:
# dmesg | grep bge
bge0: <Broadcom BCM5721 Gigabit Ethernet, ASIC rev. 0x4101> mem
0xd0200000-0xd020ffff irq 18 at device 0.0 on pci4
miibus0: <MII bus> on bge0
bge0: Ethernet address: 00:30:48:82:12:44
bge1: <Broadcom BCM5721 Gigabit Ethernet, ASIC rev. 0x4101> mem

bge1: Ethernet address: 00:30:48:82:12:45
bge0: link state changed to UP

# ifconfig -l
bge0 bge1 plip0 lo0
