Thanks! That was, what I was looking for.

Now I tried that – the physdev_dom0_hide=(02:01.0) – but it does not 
seem to work. After the reboot lspci still lists the NIC I excluded with 
the physdev-hide parameter, and the kernel of dom0 has connected it as 
eth0 like before.
Or did I misunderstand the concept? Does physdev-hide not hide from the 
dom0-kernel?

One more thing: I tried compiling a kernel for my driver domain (the 
firewall-to-be) putting in all options that I thought would make sense. 
The result is a kernel that crashes immediately on start (even with a 
standard config the xenu-kernel from option-c.com works with). I have to 
admit I am not much of a kernel shaper yet.
Could you send me the config of your firewall-kernel as a base so I 
could add my NIC and start researching from a more elaborate point? If 
so, please send it to my address directly to not bother folks on the 
list with attachments.
Thanks for your help in any case.

Dirk
