sorry about that, my first patch was more broken than i thought (it will 
basically hang on _any_ box), please try the second patch.

Note how the above hack code does a stupid goto, and 'p' is updated for 
the next loop iteration already. The second version of the debug patch 
only updates 'p' in the 'continue' case and will hopefully get you much 
further into bootup!
