Grasping at staws I looked at /proc/pci and saw the following in my
system:
Bus 0, device 8, function 0:
Ethernet controller: DEC DC21041 (rev 33).
IRQ 11.
Master Capable. Latency=64.
I/O at 0xe800 [0xe87f].
Non-prefetchable 32 bit memory at 0xea000000 [0xea00007f].
and /proc/iomem said:
ea000000-ea00007f : DEC DC21041
Since that memory region is 128 bytes I tried a patch similar to Mr.
Vandrovec:

I'm obviously out of my depth here because, while the card is now
detected and works, the results are less than satisfactory. I'll step
out of this and let the real hackers work on things. I hope some of
this helpls someone. Look at this:
/proc/iomem now says:
