OEM/Ethernet Addr set to 00:00:00:00:00:00?

Hello there-
I'm using a 3c920 card included with an Asus A7M266-DL motherboard.  The
eeprom onboard (As read with vortex-diag), says that the ethernet MAC is
00:00:00:00:00:00.  This is evidently incorrect since the card has a real
MAC address, but why isn't it being used?  Is this a fault in the driver
or in the eeprom?  I'm using the driver out of the 2.4.18 kernel:

02:06.0: 3Com PCI 3c905C Tornado at 0xc400. Vers LK1.1.16

Thanks.  Please find attached some debugging output:

$  sudo ./vortex-diag  -ee
