second realtek RTL-8139/8139C/8139C+ not detected

[DataMatrix]

I have the folloing hardware on my machine:
Attansic Technology Corp. L1 Gigabit Ethernet Adapter (onboard) [eth2]
Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (pci) [eth1]
Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (pci) <problem>

The two realtek cards are 1:1 identical. The problem is that ubuntu doesn't detect the second card, not in lspci, nor it's in dmesg. I used to have a different card there (a Reaktek 8139D infact), but it had to be replaced, so now there is a hole in place of eth0. Is there any way to get the second card working, or do I have to find a different card from different manufacturer?

Edit:
I've tried sudo update-initramfs -c -v -k `uname -r`, but it didn't work ether.
I think I had similar problem before, but it disappeared by itself back then, I have no idea how.

I've solved the problem though I'm not sure if it was the right way to go:
I've halted the machine, puled out the problematic eth out of the pci slot, started the machine again. As expected, all readings of lspci, lshw and dmesg are about the same as before, as if the card wasn't there in the first place. I've halted again and put the card back. After the machine started, I now get

lspci -nn

I remember that when I changed the old card with this new one, I didn't boot the machine inbetween, and it probably was looking for the old card where the new one was and it didn't remove it (I don't have any hard evidence on that statement). Now the new card is eth3 instead of eth0, but that isn't that much of a problem.

Should this be filed as a bug report?
