NACK, single chip flag is going out since only needed check is for
5424/2424 during nic_wakeup, 5413/2413 behave like the rest
5211/5212-combatible cards.

Sorry for delaying the relevant patches, i'm working with the 2413
card i got from Mike to make it work and it'll take some time (not as
easy as i thought, i probably miss something)...
