your card is being identified as a Intel E1000 Gigabit Ethernet. From
kernel configuration docs:

Intel(R) PRO/1000 Gigabit Ethernet support
CONFIG_E1000
  This driver supports Intel(R) PRO/1000 gigabit ethernet family of
  adapters, which includes:

  For more information on how to identify your adapter, go to the
  Adapter & Driver ID Guide at:
  
   <http://support.intel.com/support/network/adapter/pro100/21397.htm>

  For general information and support, go to the Intel support
  website at:

   <http://support.intel.com>

  More specific information on configuring the driver is in
  <file:Documentation/networking/e1000.txt>.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called e1000.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt> as well
  as <file:Documentation/networking/net-modules.txt>.
-----------------------

Basic question: has the kernel identified your network card correctly?
If so, try 'modinfo e1000' and you should be able to see what are the
options for this specific module.
