I have a Buffalo LinkStation Pro Duo in the cupboard.
I have never hacked it but I believe it is based on Orion5x.
If I can find an active serial port on the motherboard, I could test it.
Like Albert, I also have a LaCie EDmini V2, but he, being a U-Boot
expert and more familiar with DT, is probably better qualified to test it.
Unfortunately I am pretty sure that neither uses a PCI or PCIe bus.
Cheers,
Chris
