So it looks like it's not getting enabled on New World machines.
After a brief look at the driver init code my impression (quite
possibly a wildly inaccurate one BTW) is that the driver wants DMA
channels and/or IRQs already partially configured. On New World
machines booted via yaboot these may not be configured by OF. On Old
World machines booted via BootX MacOS does the initialization.
