This particular system has four onboard ports, a two port add-in card
and a single port fiber card all using bnx2, so I have some options to
try different devices if there's something different about them.
Details of all of them below.

Booting the same system back to 2.6.36 with the patch I mentioned
previously leaves me with a functioning network, so given it could be
management firmware related, why does it work on .36 but not .37 ?
The install is very stripped down, there's no udev or /sbin/hotplug
loading firmware behind my back as neither are installed. So firmware
is whatever comes with the kernel. Just having had a look, I see the
firmware provided with the kernel has changed in .37, but the output
of ethtool -i shows the same firmware being used with .36 and .37
