Ah, so I should expect only the physical CPUs to show up in cpuctl list,
and then I can pluck the apid from the 'hwid' column?

Here is what I get when I run cpuctl list on my system (amd64 domU on
xen 3.1.4, NetBSD-current):

Num  HwId Unbound LWPs Interrupts     Last change
---- ---- ------------ -------------- ----------------------------
cpuctl: IOC_CPU_GETINFO: Inappropriate ioctl for device

Whoops.
