For the current release you'll have to arrange some startup code to initialize 
some control registers.  You need to set RAMBAR correctly and PST[3:0] signals. 
  These are initialized by the debugger for you.  The following untested code 
sequence should do it:
	move  #0x20000021,%d0
	movec.l  %d0,%rambar
	move  #f,%d0
	move.b %d0,0x40000000+0x100074

You'll need to edit this into crt0.s.

Our Fall release will make this automatic.
