Log:
  Improve the smp-support question wording for the modern era.  Indicate that certain ARM cpus may have issues.
  
  This is based on information and wording from gavin.

-	    <para>&os; will take advantage of HyperThreading (HTT)
-	      support on &intel; CPUs that support this feature.  A kernel
-	      with the <literal>options SMP</literal> option, enabled

-	      will automatically detect the additional logical

+	    <para>&os; supports Symmetric multi-processor (SMP) on all
+	      non-embedded platforms (e.g, i386, amd64/x86-64,
+	      ia64, sparc64, powerpc, powerpc64).  SMP is also
+	      supported in arm and MIPS kernels, although some CPUs
+	      may not support this.  &os;'s SMP implementation uses
+	      fine-grained locking, and performance scales nearly
+	      liniarly with number of CPUs.</para>
