Well, don't worry about that comment in German. I put it in,
when I was not sure about a reported problem being real, but
that comment is of no good use to anybody anymore :)

The address range seems to be invalid for a memory mapped 
region, since it obviously conflicts with system RAM. As 
somebody else already mentioned, this might actually be a
port map, but there should have been a warning that you 
are trying to map a "bad memory type".

Please send me a *verbose* boot message log and your attach
code, at least the part that contains the call to pci_map_mem(). 
This will allow me to understand what's going on ...
