You mean you get only 2 of the 4 ports for both cards, right?

You can re-do the udev rules for the network interface so it starts by 
eth0 and so on.

Me neither, it seems the 4 NICs are properly detected.

Things I would check:

1/ BIOS (to verify the embedded NICS are not making noise)
2/ Kernel (test with a LiveCD featuring one of the latest kernels available)
3/ "dmesg | grep -i eth" (for possible driver errors)
