Ok, this is running afoul of a recent change to attempt to get cardbus
fxp's working (which have a different sized EEPROM).

I tested a change from Johan Danielsson on what's really an 82559 on
my laptop, but clearly that's not the same as the real thing..

Johan -- you did the orignal change in PR8631.. could you track this
down and figure out something which works for both Patrick and for
your cardbus fxp's?

Patrick: in the meantime, could you try applying the enclosed patch to
i82557.c and rebuilding a -current kernel?

(this is edited down from the actual diff between 1.9 and 1.10 of
i82557 to just back out the part which attempts to auto-size the EEPROM).
