Ok so it works fine for me with the HP microservers.

ubuntu at maas:~$ ipmidetect -d -s
10.0.0.101 10.0.0.102

We need to talk about this - unless we can match BMCs to hardware before
we enlist nodes, it makes this detection less useful than it could be.

The closest thing I can see is the "fru" command which lists "Field
Replaceable Units" but on the microservers you don't get a lot of info:

ipmitool> fru print
FRU Device Description : Builtin FRU Device (ID 0)
 Product Manufacturer  : HP
 Product Name          : MicroServer Remote Card
 Product Serial        : 000000000000000

I'll try in the lab later (I can't get in right now).
