Subject: NIC driver r8168 with r8169 for RTL8111/8168B and DGE-528T together

Hi

I would like to use my onboard NIC (eth0) with its r8168 driver from 
RealTek together with my D-Link NIC (eth4=eth1) with its r8169 default 
driver from the install. Sepatately they seem to work...but I would like 
a firewall set up with NAT and had it before I "upgraded". ;^)

2 Questions:
1) How can / should I modify the rules (in /etc/rules.d ?) and apply 
them for the kernel to load both drivers? (Even if it is just temporary 
until next update and I have to apply it again)
2) Are there still known issues with instability of the r8168 drivers 
(as per Ubuntu bug lists)?

Here follows ALL the info I though was relevant(?).
I am running Ubutnu 11.04: uname -av
Linux weer 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011
