Apologies for not providing 100% of the details.  The numbers from
/proc/net/dev match ifconfig (I did check that) and all my hubs light
up solid with collisions as a physical manifestation of the problem

Unfortunately this is not the case here.  Other 10baseT hardware
in the same machine does not exhibit the collision behavior.  I'd just
rather be running a Tulip (as I plan to go 100baseTx in the future)
even if a 3c509 already works properly but I have to play with the
Tulip some.

I'm beginning to think the transmitter in this card may just be woogie.

Thanks for the stab in my direction ;-)  Nice to know folks are listening.
