I can't get it to work though on a MacBook, but others have had success.

Title:
  SysRq key equivalent needed

Status in Mactel Support:
  New
Status in “linux” package in Ubuntu:
  New

Bug description:
  MacBook keyboards and other Apple keyboards lack a SysRq key and
  therefore lack important kernel functionality that is designed to save
  catastrophic data loss if the computer freezes.  An equivalent
  keystroke should be assigned, for example Fn + Eject, to preserve the
  functionality of the Magic SysRq key in linux on a Mactel.  I believe
  this is a bug and not a feature request because the current
  implementation assumes that all keyboards have a SysRq key which is an
  incorrect assumption and therefore a mistake, or bug.
