Look at the RTAI project, which is close to RT-linux project with
SMP extensions .

I use it on Dual-PIII, and assign tasks to specific processor
and attach irq to specific processor too.
only 2 functions to manage it :
void rt_set_runnable_on_cpus(RT_TASK *task,unsigned int cpu_mask) ;
and
int rt_assign_irq_to_cpu(int irq,int cpu) ;
-> the cpu_mask allow you to set task runnable on CPU #2 & #3 but not on
CPU #1 for exemple.
Good Luck.
