The tunables only affect what the kernel uses (i.e. it shouldn't panic on boot 
anymore).  It will not affect the output of mptable since what these tunables 
do is tell the kernel to not even look at the mptable or any other routing 
information and just hardcode the IRQ values.

Don't do this.  These should only be specified in loader.conf, not in a static 
hints file.  Static hints files are not really recommended.
