The main problem was that the openfirmware stuff is ported from FreeBSD
and someone (don't remember exactly who, possible that it was me)
suggestet that the ported files should be placed in cpukit rather than
in the BSP section. With that it's quite hard to use the interfaces in a
BSP driver without installing some headers.
