and even more funny is that the slot is standard form factor that can easily be confused with another widely used standard. so what happens if a dumbnut puts a pcie card into that slot? does warranty covers that, i wonder?
I was under the impression that, while the slot is physically the same, it's aligned differently so you can't put a standard PCI-e card in the slot and have it match up with the backplane, and there's a PCI-e x1 slot in front of it. So, only a PCI-e 1x card will fit, and if you fit one of them it will work as expected, but will block use of the Xorro slot. No damage done. Similar to the ISA and Zorro slot layout on big-box Amigas... That's how it looked in the board layout pics that were floating around a while back anyway.
Edit: I see you don't take billt's word for it, so you probably wouldn't take mine either so. Far too easy to jump on the bandwagon. Anyway,
here's a pic of the top of the PCB. You can more easily see there how it's laid out to avoid just that confusion, and to allow the use of PCI-e x1 in that slot.
