Is there anybody that has run the PrPMC800 as NON-MONARCH (and been able to
use the Ethernet). When I try to run a kernel that runs OK as MONARCH, it
fails as a NON-MONARCH. As far as I can understand that is due to

   1. The Harrier is not device 0 on the PCI bus, instead the host PCI
      is picked up (and discarded 'Host bridge 0x48011057 not supported').
   2. The wrong ethernet controller is picked (one that is owned by the pci

Is it at all possible to run this board as a NON-MONARCH and use the
Ethernet-controller if the MONARCH of the PCI-bus is not aware of this (the
card is to be used in a system where the operating system of the MONARCH
can not be changed)?
