Is there a way to direct specific interrupt 
activity to a single processor, or to tune the
behaviours in any way? It seems absurd that there
is no networking benefit to adding another
processor two years into the project.

	Unless you are ready to write support for interrupt affinity, cleanup
	the APIC code to use logical topology and do the necessary cleanups to
	the PCI interrupt routing code, these things take time.
