That would be neat for Catalyst board owners. Particularly PowerCenter
folks since the new DIMM could do the "PCI Timing Update" in ROM and also
identify the PowerCenter differently from the 7200.

It would also be nice to have a real, working version of OF rather than the
half-done Apple version. Maybe an internal video driver node so that one
could boot up like those with the chaos are able to?
