For some globus GRIS scripts, I'm using the sysctls
vm.stats.vm.v_page_size and vm.stats.vm.v_page_count to get memory size.
I'm calculating free memory (a bogus concept in FreeBSD) as
total-active-inactive-wired, all of which are available under
vm.stats.vm.   Swap information is available from the swapinfo command.
If you really need it in an API you could just steal the code.

The number of cpus is easy as it's just the hw.ncpu sysctl.  Other
information is currently difficult to obtain and I'm currently parsing
the output of the cpuid port to obtain a fair bit of it.  The only
source of Mhz is /var/run/dmesg.boot.

Load is available from the sysctl vm.loadavg.
