Okay,

I hope I don't forget anything...  I'm using a centris
650/150AUX/25mhz.  I have built in video on one bit, extensions off, all
other portions of BSD loaded (ect12 - base12) I loaded the latest
ABDTest kernal and it hung in the same place as other 040 brothers did. 
Here's the list:

Bootstrapping NetBSD/Mac68k.
Faked range to byte 0x1000000.
Bootstrapping the Pmap system.
Pmap Bootstrapped.
Moving RomBase from 0x408000000 to 0x987000.
Video address 0xf9001000 -> 0xb87000.
