How to talk to a local IPMI under OpenBSD.

Much like Linux, modern versions of OpenBSD are theoretically able to talk to a suitable local IPMI using the standard ipmi(4) kernel driver. This is imprecise although widely understood terminology; in more precise terms, OpenBSD can talk to a machine's BMC (Baseboard Management Controller) that implements the IPMI specification using one of a number of standard interfaces, as covered in the "System Interfaces" section of ipmi(4). However, OpenBSD throws us a curve ball in that the ipmi(4) driver is normally present in the default OpenBSD kernel but not enabled...
