    could you try running
    ifconfig -a

    Open in new window

    this should list both active and inactive devices you can also try running
    dmesg | grep "eth[0-9]"

    Open in new window

    to see what is going on early on with device name assignment for the ethernet adapters.

    if you could report back your findings from these

    First of all if your run


    it will update your pci definitons. After the update I believe you'll be  seeing both adapters with a correct name.

    After you have an id for the your Intel adapter you'll be able to download a driver from the Intel site.

    Both of your adapters should be picked up by the same standard kernel driver, the e1000e. I would where possible try to ensure that your kernel & modules are the latest available for that distribution as there are reasonably frequent updates to the driver and the devices that it supports. RHEL 5.1 contained v7.3.20 of the e1000 driver which doesnt support the 82578 series. It looks like it should be supported in RHEL 5.4 and above.

    As KeremE mentioned you may be able to get a binary driver from Intel for your current kernel rather than updating RHEL
