The Ethernet NIC isn't supposed to have a firmware, right? Else it would have a flash chip connected to it, right? It still has a very small eeprom for its configuration bits, and I think some bits are documented in some intel datasheets. I hope that: * The computer is properly powered off when on battery, and that the NIC and its led are also off during suspend to ram. * There is no firmware or such that I missed, because I guess that this NIC can do DMA.
