To continue this saga:
Card is a Cogent 'EM110 TX PCI'.
Machine is a Digital Celibris XL 5133 with the latest BIOS (2.04).
'ifconfig de0 down ; ifconfig de0 up' has no effect.
BIOS has no option to set 'Master Enable' or similar.
Have tried two other de card - one an earlier Cogent, and one a later
version (after the company had been taken over by adaptec).
Both work fine - the difference in dmesg output between the failed de0
and the working later de0 is:

I notice the problem card enables 10baseT immediately, while the
working one does it later. Also its a different rev (2.0 vs 2.2)
Does anyone have any idea of how I can approach this? Is there
some bug in the 2.0 chip which needs some workaround?
We have a number of machines with the problem cards in which we
cannot reasonably swapout... :/
