The chipset is not necessarily the same in the second example (different revision); RTL8111/8168B is not RTL8168d/8111d. They probably do use the same driver but I'd need to see the Vendor:Device ID pairing to know for sure.
Eth1 is an xpci card sold by StarTech. A system with an identical card reports this:

The 4 port serial controller on the second host does not have an equivalent card installed on the host that no longer recognizes eth1. The integrated NI is eth0 for both hosts and this i/f is integrated on the Intel motherboard. The motherboards are the same model in both hosts. Both system are configured as KVM hosts. Both are running CentOS-6.3

OK, I'd definitely try reseating the card and if you still get no joy I'd swap it out for a replacement.

kmod-r8168 is the correct driver for this device. If you'd like to try the updated driver from elrepo, just install kmod-r8168 and reboot.
lsmod should then show r8168 in use and not the native kernel driver r8169. Many have found this driver to be more reliable than the native kernel driver, assuming the hardware isn't defective.
Hope that helps.
