hmm, you mean if you simply remove 'of_call("quiesce", 0, 0, NULL);'  
from boot_of.c you get further?!
Are you still closing /chosen/stdout and /chosen/stdin?
I see there is logic there and we only close stdin if (stdin !=  
stdout), I wonder if there is a reference count?

I would agree, because by the time you have scrubbed memory in Xen,  
OF has been destroyed.
One thing you might try is specifying the baud rate in ns16550_init 
(). perhpas SLOF changes it?
