Sorry for the slow response, and thanks for the patch!

We have tested it here and it seems to be working fine now - the IPMI
stuff no longer initializes system interfaces, and hence doesn't get
in the way when going into suspend or reboot later.

This is a consumer desktop platform, so if some kind of IPMI
functionality is really present in the hardware then it is not really
going to be relevant for the ordinary user. So it should be fine to
just ignore the hardware as you have done.

Thanks
Daniel
