My patch does not do the SMBus variant, as that would need to go into an 
SMBus device, and I haven't worked at all on an IPMI device to do this.

The fields that are dynamic are:

_STR - A string identifying the interface type (optional, but recommended)

_CRS - This can be a I/O or a memory address, and an interrupt may or 
may not be here.  I have not done the work to add the memory bus, as my 
qemu patch does not support that yet.

_IFT - An integer that identifies the interface type.

_SRV - Identifies the IPMI spec version the interface complies to. It's 
generally best to use the actual version; if you used a newer version 
then an old driver may not work with it.

If more than one interface is added, then the _UID field becomes 
important, but there's no support for that at the moment.
