I am not certain but I have tried to enable MSR_DR and was still able to
print to the serial console.

It seems that execution stops when calling rfi in
arch/ppc/kernel/head_4xx.S. I have put the sample code provided to
output a single character on the serial port immediately

before the rfi

quoted

call and after the after the start_here label. Only the

first is beeing

quoted

executed. Any ideas?

Are you sure that the code that print a char on the serial
port works also
with MMU enabled ?
