Narendra Sankar indicated that they had a similar problem with a
managed Cisco 2900 Catalyst managed switch.  Apparently this
particular switch runs spanning tree protocol which according to Cisco
can take up to 30 seconds to complete.  They added a sleep > 30
seconds to the network startup scripts and have had no problems.

I have not tried this yet.  Our switch is an unmanaged Netgear 8
port.  Is it common for STP to be used on all switches, or only on
managed switches?

Paul Claessen suggested to check that the card is properly configured
for auto-negotiating using 3c90xcfg.exe that came with the card.  I
have not done this, but /var/log/messages contains:

I'm not sure, but it seems that the third line indicates that
autonegotiate is enabled.  Am I wrong in thinking this?

Also, FYI, the switch DOES light up indicating that there is a valid
100 mbps link when the cable is connected, so it does seem that the
hardware is negotiating 100 mbps correctly.
