You are in the black magic area.  If you have a simulator, you can use
that.  Otherwise, since you presumably have a working kernel, you can
usually hack print statements by using inline assembler to do a direct
invocation of the write system call.  If that doesn't work, the next
step is probably hand simulation of the instructions in the suspect
