Where a my ethernet adapters?

Hi!

I'm a little bit confused about my network adapters. I'm runnig  
debian on an oldworld G3. Beside the built-in ethernet adapter, I  
have a second one  plugged into the PCI bus.

running lspci:

0000:00:00.0 Host bridge: Motorola MPC106 [Grackle] (rev 40)
0000:00:0d.0 Ethernet controller: Winbond Electronics Corp W89C840
0000:00:10.0 ff00: Apple Computer Inc. Heathrow Mac I/O (rev 01)
0000:00:12.0 VGA compatible controller: ATI Technologies Inc 3D Rage  
Pro 215GP (rev 5c)

Now only one ethernet controller is shown. Is the the built-in one?  
Where is the second one?

Regards,
Martin
