em(4) on FreeBSD is sometimes annoying

The focus here on the laptop distracted me, but someone else at work
reminded me. Its very important that you run the EEPROM fix for
the 82573 that i posted a long while back, search in email archive
for it. Its a DOS executable that will patch your EEPROM.

I am not sure if the Lenova's need it, but get it, run it, and then
see if your problem goes away.
