Adaptec ANA6911a not working w/ tulip driver, but works with de driver

I have an Adaptec ANA6911a (10/100 TP, 10base2) connected to a 10mb hub.

The card has a tulip (21143) chip in it. (21143-PA / 21-44085-10); The
other prevelant chip on the board is a (DP83840AVCE)

The tulip chip had a sticker on it with:

1633600 D

The card DOES work with the de4x5 driver, and with win9x {but I would
much rather have it working with the tulip driver}:

eth0: DC21143 at 0xec00 (PCI bus 0, device 9), h/w address 00:00:d1:1b:bc:29,
      and requires IRQ10 (provided by PCI BIOS).
de4x5.c:V0.543 1998/12/30

RH 6.0 detects it as a tulip, but the card does not work (link light on
hub stays off). Tried the driver in 6.0, and all the .91 drivers
(including the latest  test driver)

PCI bus /proc/pci shows it as:
Bus  0, device   9, function  0:
    Ethernet controller: DEC DC21142 (rev 33).
      Medium devsel.  Fast back-to-back capable.  IRQ 10.  Master Capable. Latency=96.  Min Gnt=20.Max Lat=40.
      I/O at 0xec00 [0xec01].
      Non-prefetchable 32 bit memory at 0xe7800000 [0xe7800000].

With the tulip driver it is detected as:
