Hello Jim,

I can tell you that I also have attempted to use a Netgear FA511 CardBus PC 
Card with both Donald's driver and, in my case, the kernel 2.4.18 driver. I 
have had no success either.  The appropriate modules load OK, occasionally 
ping bytes are transmitted but few if any are received.  I would like to see 
this card working but for now it is sitting on the shelf.  I have gone back 
to using an NE2000 card.  Others have reported on this list of failure with 
this card.

The following are my results.  You will notice that the eeprom contents have 
come up empty.  On some occasions the eeprom contents were present but still 
the card did not function.
