Hello Bjorn
Firstly sorry for not being=A0able to join in this discussion, I have been
moving house and only got my X1000 set up again yesterday..

Actually the root ports on the Nemo's PA6T processor don't respond to the
SB600 unless we turn on a special 'relax pci-e' bit in one of its control
registers. We use a small out of tree init routine to do this, and there
would be the ideal place to put a call to
pci_set_flag(PCI_SCAN_ALL_PCIE_DEVS).
This patch fixes the last major hurdle to getting the X1000 fully supporte=
d in
the linux kernel, so thanks very much for that.
Regards
Darren
