I'm having a problem with the DC21140 10/100 PCI ethernet adapter whereby 
the driver appears to read but misinterpret the ROM on the card:

/kernel: de0 <Digital DC21140 Fast Ethernet> rev 17 int a irq 10 on pci0:9
/kernel:   reg20: virtual=0xf4786000 physical=0xfbfff000 size=0x80
/kernel: de0: can't read ENET ROM (why=-4) 
(00000000000000000000000000000000000001010000f80007a1004100444535
/kernel: de0: DC21140 [10-100Mb/s] pass 1.1 Ethernet address unknown

The string returned in the message does include the adapter's ethernet
address, which makes me suspect that the problem may just have to do with
adjusting an offset somewhere so that this can be interpreted correctly. 

Any ideas?  It seems like I'm real close to having this working...

SOFTWARE:
 	2.0.5-950622-SNAP, problem also appears with the 2.1.0-950928-SNAP
        boot floppy.

HARDWARE:
	ASUS P55TP4XE, P100, 32mb RAM

	    PCI BUS
                1 SC200 NCR SCSI - IRQ 11
                1 DC21140        - IRQ 10

            ISA  
                1 Generic VGA    - IRQ 1
                

NOTES:

	The DC21140 can run and pass the extensive diagnostic suite
        included on the DOS install diskette - this on the same hardware.

        Removing the SC200 from the PCI bus and booting the machine from
        floppy does not mitigate the problem.  

        Enabling all shadow memory ranges in the BIOS doesn't help.
