Ask and ye shall receive.  The outputs are attached.  I have both the  
'before' and 'after' sysctl outputs for your reference.  I looked at  
the ofwdump output when making the patch, and nothing obvious jumped  
out at me.  I chose 'cpu' because I read online that the ds1775 is on  
the CPU card for the G4 MDD.  I don't know if there's any other that  
has the same problem, so a default to 'cpu' seemed sufficient to me.
