That's strange -- it's a NetGear card, right?  It might be just the name
list, which is frequently wrong.  What are the numeric values for IDs?
(Use the '-n' option.)

It is only needed if you are using the original PCMCIA code.
Unfortunately, there is no good way to detect that at compile time.  So
the Makefile unconditionally builds the module.

  The card is not working.  ping says:

It's work a little bit... that narrows down the problem.

That's curious!  I'm guessing that there is an error message from the
CardBus code, likely earlier in the boot sequence.

This is a Bad Thing.  The driver had to make up a station address.  If
the EEPROM is really erased or missing, card-specific NIC parameters
have not been loaded.

What does 'mii-diag' report?

Normal operation so far.

Hmmm, something is wrong.  The chip did manage to load the subsystem ID,
so part of the EEPROM is programmed.

What similar issues?  I haven't noticed another error report that matches
this one.
