  I'd say yes, definately send a PR.

  The SP displayed is meaningless due to a bug in the code that displays
this message.  I have fixed this so that the original SP at the time of
the exception is displayed.

  I have also added a display of the wired TLB entries used to map the kernel
stack so I can get a verification that the TLB entries are correct [or what
they are if they are incorrect].

  These changes should be available in the next SUP.  Anyone getting this
panic with a kernel with these changes please send me the output between
the "ktlbmiss" and the "panic".
