You will find that the NIC is initialized quite late in the boot process.
I think that is likely to be the problem here.
If you enable the NIC with netconsole, it will initialize much earlier in
the boot process.
You could give that a try, if it solves the boot time problem, you can then
look at how netconsole works, and just implement the initialization of the
NIC card, without sending console messages to the network.
