Unfortunately, it doesnt work for me on the p630:

PCI: Enabling device: (0000:00:03.1), cmd 141
PCI: Unable to reserve I/O region #6:10@0 for device 0000:00:03.1
pata_sl82c105: probe of 0000:00:03.1 failed with error -16

Any idea how to fix it properly?

That looks like a compiler bug.

I/O region #6.

pci_request_regions() and pci_request_selcted_regions() end up in a loop
calling pci_request_region with the values 0 to 5. Never 6.

Can you instrument that code a bit and see wtf is going on first of all.
