Right.  Did you rm -rf /etc/udev/rules.d/70-persistent-net.rules

I highly doubt it's an issue of driver.   You should be able to toss 
pretty much any NIC in a box and it will be recognized.  My guess is 
that you did not remove the OLD nic's from udev, so the new ones are 
getting configured as eth2 & eth3.   That's most likely.

Just do as Michael suggested and reboot.  Then you'll be good to go.  If 
not, then it's a NIC problem.

Oh, and when you reboot, get into the bios of those NICs and turn off 
their firmware.  My guess is you don't want to boot your box from the 
NIC (ie: pixie boot) so that stuff is just taking time on your boot 
sequence.   I make a habit of disabling that whenever possible.
