Yes, the patch workes fine and I have for my LOM's (rev 0x0d):

fxp0: <Intel 82550C Pro/100 Ethernet> port ....
fxp0: Compatibility word : 0X0d13
fxp0: EEPROM ID word : 0X5060

and for two external cards (rev 0x0c)  I see

fxp1: <Intel 82550 Pro/100 Ethernet> port ...
fxp1: Compatibility word : 0X040b
fxp1: EEPROM ID word : 0X58a0
fxp2: <Intel 82550 Pro/100 Ethernet> port ...
fxp2: Compatibility word : 0X020b
fxp2: EEPROM ID word : 0X50a0

Thank you for investigating in this problem.
