No. I don't believe it is. None of the other cards have this value.

I am sure you are correct. Looking back through my logs, the first
time I booted up with this card (driver 0.89H) the entry was:

Dec  3 12:58:55 delta.local-net linux: eth1:  Index #1 - Media 10baseT-FD (#4) described by a 21142 Serial PHY (2) block.

On subsequent boots, the entry had changed to it's current value.

This machine doesn't use modules. I've enclosed below the debug
messages for another machine tah does.

Not the identical symptoms. Another card is not put into a usable
state by 0.91. Indeed, it is left in an unusable state and
will not work with 0.90p afer rebooting/resetting.
This card is in a dual-boot W95 machine - booting up W95 gets
the card working again.

Here is the debug=3 klog and tulip-diagnostics for this
card:
