This can be done.  Look at /proc/irq/{number}/smp_affinity

This file contains a hexadecimal map of which processors to use.  To
lock down to the first processor, I believe you can:

echo 00000001 > /proc/...

And the second:

echo 00000002 > /proc/...

And the third:

echo 00000004 > /proc/...

If you've got a handle on bitmasks, you get the idea.
