I see your NIC is at IRQ 3 ... and if your ethernet is active, and you
say it is, 0 Rx packets means the kernel can't get at your NIC.  I will
bet that you have a conflict with a serial port.  Try moving the NIC to
IRQ 10 or something, or remove the serial port (this is not always
possible).

Try that and see what you come up with.  I think if you move the NIC
card IRQ you will start to receive packets.

btw, removing serial support from the kernel and/or not loading the
serial module is not enough to solve this conflict ... I've had this
problem before.
