Allright, so that's an out of tree userland thingy... (which may well
work on ppc too I suppose). Definitely not installed by default by my
distro so IRQs from the network cards on all x86's using ubuntu gutsy at
least are spread to all CPUs :-)

There's also a balance kernel thread in x86 with has a notion of irq
that isn't moveable but that flag isn't set by any driver.

Cheers,
Ben.
