(Get the code!)
I tested some more kernels from the ppa mentioned on the page referred to by comment #12
The last one to work for me is a 2.6.35 maverick kernel.
Problems start from 2.6.36 onward, i guess that's where the pvops block driver has been included.
(i tested latest versions of 2.6.36, 2.6.37, 2.6.38 and 2.6.39 available in the ppa)
My guess is that pci passthrough with pvops never really worked at all in mainline kernels (for some of my hw that is).
2.6.37 shows something new:
[ 1.490097] ACPI: bus type pci registered
[ 1.492766] PCI: Using configuration type 1 for base access
[ 1.496987] bio: create slab <bio-0> at 0
