Alex pointed out that IBM interprets the spec the same way that HP does.
Are there any other machines that follow the spec the same way that
Fujitsu does?

I hadn't realised that patch got in to put the bus name in as a
uniquifier. I thought we'd rejected it because the problem only
occurred on one box with bad firmware.

That is the plan. I'm not sure why the shpc slots aren't renamed in
this revision of the patch -- maybe Alex dropped that part?
