hwloc-gather-topology does not gather I/O devices unfortunately (we
could gather OS devices, but we can't for PCI devices).

What do you have under /sys/bus/pci/devices/<yourpcibusid> ?
Do you see anything like hostX in there? What does in contain? Can you
walk in there until you find a "block" child?

I haven't tested on recent kernels lately, maybe something changed in
the sysfs hierarchy, I am booting a 3.5 to check things.
