Hmm, did some more testing:
did a rmmod r8168 and (after "un"blacklisting the r8169) modprobed the
r8169. This time r8169 came up nicely but with a complete different MAC
(forgot to not than one though).
So I guess the vendor compilation did other stuff besides just compiling
the r8168 kernel module.

Did another test:
blacklisted the r8168, renamed r8168.ko to r8168.bak, depmod -a and
powercycled the system. Funny it came up with both r8168 and r8169
loaded and I got my intended IP address from. DHCP, so r8168 somewhat
got loaded and used his MAC.
Did another rmmod r8168, rmmod r8169 and then modprobe r8169.
Even though I did NOT configure a MAC address myself manually it came up
with a new MAC address and of course got a dynamich IP address.
So I don't know where the vendor somewhat changed something (with his
compiling/installing) to the effect that r8169 now works?!?

Karsten
