As another data point...

I have a VME-7805 processor board
(http://www.gefanucembedded.com/products/1151) running NetBSD 4.0 and
I'm also having problems getting the wm0 interface working. The LED on
the port lights momentarily, but then goes out and no traffic is
possible through the interface. FWIW, it doesn't work even when I
force the interface down to 100baseT.

'dmesg' output:

wm0 at pci1 dev 6 function 0: Intel i82540EM 1000BASE-T Ethernet, rev. 2
wm0: interrupting at irq 9
wm0: 32-bit 33MHz PCI bus
wm0: 64 word (6 address bits) MicroWire EEPROM
makphy0 at wm0 phy 1: Marvell 88E1011 Gigabit PHY, rev. 3
makphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT,
1000baseT-FDX, auto

Has anyone else used this version (EM) and this PHY successfully?
