Core Duo - only one cpu being used

[Eric Anderson]

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 
                     up 0+01:20:55  21:05:47
100 processes: 2 running, 98 sleeping
CPU states: 47.4% user,  0.0% nice,  1.3% system,  1.3% interrupt, 50.0% 
idle
Mem: 383M Active, 391M Inact, 154M Wired, 34M Cache, 110M Buf, 25M Free
Swap: 2048M Total, 2048M Free

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

dev.cpu.0.%desc: ACPI CPU
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=\_PR_.CPU0
dev.cpu.0.%pnpinfo: _HID=none _UID=0
dev.cpu.0.%parent: acpi0
dev.cpu.0.freq: 2005
