Forgive me if I've missed this on a list somewhere, but My new laptop
with a Core Duo doesn't seem to use both CPU's. It sees both, but I
never see anything on cpu 1. Here's a top snippet:
last pid: 20852; load averages: 1.31, 1.27, 1.00

100 processes: 2 running, 98 sleeping
CPU states: 47.4% user, 0.0% nice, 1.3% system, 1.3% interrupt, 50.0%
idle

All processes are on cpu 0. Output of sysctl dev.cpu shows:
