The lack of PCI domain support on x86-64 prevents me from seeing the following devices on the PCI bus:

I get the following errors, unless I disable the BIOS option 'ACPI bus segmentation', which is enabled by default (and will be enabled on most future machines):

Full machine info was just posted in another message, subject "[2.6.15-rc4] oops in acpiphp".
Is this a bug? Is this expected behavior (not implemented yet)? A jump-start on tracking this down would be appreciated.
Based on the logic in arch/i386/pci/acpi.c (which is shared with
x86-64), it's just not implemented yet at all.
I don't know of anyone currently working on adding this support to this
code, does anyone else?
