There is a file called com.apple.boot.plist in /Library/Preferences/SystemConfiguration
Drag it to you desktop and open it up.

You should see something like:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Kernel</key>
    <string>mach_kernel</string>
    <key>Kernel Flags</key>
    <string></string>
    <key>Timeout</key>
    <string>5</string>
</dict>
</plist>
Find:
Code:
<key>Kernel Flags</key>
     <string></string>
and add the boot-flags here so in your case it would be:
Code:
<key>Kernel Flags</key>
<string>cpus=1</string>
Generally while Im setting up a machine I add -v to start up in Verbose Mode that way I can see whats going on. so
Code:
<key>Kernel Flags</key>
<string>cpus=1 -v</string>
Save the file and then drag it back into the folder. It will prompt you to Authenticate and then ask you if you want to overwrite the file. Do this and it should work fine.
