I have a Supermicro box with an X5DAE motherboard here, and the only way
I've ever gotten the on-board i82545EM to work was to plug it in to a
10mbit hub and wire "media 10baseT" in my ifconfig_wm0 line. Otherwise
the symptoms sound similar to yours. Using "auto" or hard coding any
media type failed.
An Intel Pro/1000 Server PCI-X i82545EM works just fine however. From
