Doesn't solve the EEPROM checksum problem, but printing the status
output works:

Before suspend:

em0: <Intel(R) PRO/1000 Network Connection, Version - 6.2.9> port
0x8000-0x803f mem 0xc0200000-0xc020ffff,0xc0240000-0xc025ffff
irq 11 at device 1.0 on pci2
STATUS 0xc380

After resume:

em0: <Intel(R) PRO/1000 Network Connection, Version - 6.2.9> port
0x8000-0x803f mem 0xc0200000-0xc020ffff,0xc0240000-0xc025ffff irq 11 at
device 1.0 on pci2
STATUS 0xffffffff
em0: The EEPROM Checksum Is Not Valid
em0: Unable to initialize the hardwar

Is assume that's bad :)
