What NetBSD version are you running ?

I have similar hardware:
wm0 at pci0 dev 25 function 0: 82801I (AMT) LAN Controller, rev. 2
wm0: interrupting at ioapic0 pin 21, event channel 5
wm0: PCI-Express bus
wm0: FLASH
wm0: Ethernet address 00:1e:4f:98:5d:a4
igphy0 at wm0 phy 1: i82566 10/100/1000 media interface, rev. 0
igphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 
1000baseT-FDX, auto

and it's fine with -current and netbsd-4
