Erlang, OpenBSD and multicore

I am using OpenBSD as an OS on my server, and Erlang as well. I am
considering now to upgrade to an Intel dualcore platform, taking
advantage of OpenBSD support for SMP (see ). I understand that Erlang won't
automatically detect the dualcore with OpenBSD (as it would with some
Linuxes). But will everything be OK if I "force" the CPU topology with
erlang:system_flag()? Or is there a known supportability issue with OpenBSD?
