The cdm driver doesn't need to do anything, I just wanted to check
how the clocks were set up to try and track down why ohci locks up.
The bestcomm driver is just a placeholder for now.
The ata driver is closest to working, I think it needs some helper
functions like those in the ninjaata32 driver. It finds the disk but
interrupts time out.

Because without it I lose any debug output. I have some ideas why but
haven't fixed it yet.
When the psc uart driver works then the ofcons code can be deleted. The
plan was to get to the point where I could telnet into it then fix the

Ok, thanks. I guess the next thing to try is a macppc kernel with
everything except the ofw_consinit.c changes.
