Without lgrp support, unfortunately yes: the processor_bind solaris interface only permits to bind to one processor.

With lgrp support, on should be able to bind oneself to sets of whole
NUMA nodes. I don't know any interface which would provide a granularity
between one processor and one NUMA node.
