Try the man pages for the taskset command on  Linux 2.6 machine.  There are also system calls sched_setaffinity() and sched_getaffinity()

Excuse my ignorance, please, but can someone tell me how to do that on Linux (2.6 kernels would be fine)?

The kernel scheduler -- as opposed to a cluster scheduler -- is a complete black box as far as I know.

While I am it, where do I find a minimal list of processes necessary to run a cluster node.  I can't see any reason to run the PC Smart Card demon, pcscd, but I don't know what else I can pitch.
