Absolutely not.  That's why I said:

   "Whether the kernel knows what to do with the hardware or not, it
   should at least see a PCI ID."

Just because I tell you I have a Rubik's cube in my hand doesn't mean
you know what to do with it.

To state it mathematically, the kernel knowing the PCI ID of your device
is a *necessary* condition for the device to be functional.

It's simply not a *sufficient* condition for the device to be

Can't help you there.  But getting PCI devices to work on Linux is
usually very easy with the help of:

   1. Google
   2. The Ethernet HOWTO (if it's a network card/chipset)

Getting devices to work is basically:

   1. Get the name or chipset of the hardware.
   2. Google for the appropriate device driver.
   3. Compile the driver if it's not already compiled.
   4. Load the module.

Although I don't know much about your chipset, the fact that the light
doesn't come on is a very bad sign.

The fact that the kernel knows the PCI ID of the device is encouraging.

Do you know what module is required for your Gigabit device?  That's the
first step.
