Well, I guess the only option missing in debian -generic flavour is the
CONFIG_PREEMPT, right?  At least my 2.6.39-2 is already using CONFIG_SMP
and CONFIG_IRQ_FORCED_THREADING by default.

Not sure about the rational behind picking CONFIG_PREEMPT_VOLUNTARY
instead of CONFIG_PREEMPT, but I would say that it could make sense to
at least evaluate the possibility to change this.
