I don't think its a conflict. The card is not detected at boot.
It shows up in /proc/pci though. Here's its entry.


  Bus  0, device   9, function  0:
    Ethernet controller: Unknown vendor Unknown device (rev 16).
      Vendor id=1113. Device id=1211.
      Medium devsel.  Fast back-to-back capable.  IRQ 10.  Master Capable.
  Latency=64.  Min Gnt=32.Max Lat=64.
      I/O at 0xe400.
      Non-prefetchable 32 bit memory at 0xe6000000.


I tried out tulip-diag with the following results.

#./tulip-diag
Unable to find a Tulip card in /proc/pci.
If there is a Tulip card in the machine, explicitly set the I/O port
address
  using '-p <ioaddr>

#./tulip-diag -p 0xe400 -a

vendor and device id.

Hmmm ... While I was writing this I took a visit to Acctons home page at
http://www.accton.com.tw and low and behold there's a linux driver
for it just sitting there. I'll have to take it home and try it
out. It wasn't on the disk that came with it.
