Hi moonman
I PM'd you, basically wanted to say that if you search for "kirkwood_pcie_init" in a Debian patch for NSA310/320 here
https://raw.github.com/peeter123/NSA310-320-debian/master/patch-3.6.9-nsa310.diff
and compare to
https://raw.github.com/archlinuxarm/PKGBUILDs/master/core/linux-kirkwood/archlinuxarm.patch
there is no init for the pci.
It doesn't stop 320 from starting ethernet but it does the 310
