While booted normally, in Utilities, open Terminal and enter the following:
$ sudo nvram boot-args="cpus=1" to disable
To re-enable the 2nd cpu *$ sudo nvram boot-args=""*
To get the Processor Pref Pane back, download CHUD.
Run the deinstaller, and then install.
The Pref pane should then be there in System Preferences.
Download CHUD here:
