Log:
From: Blue Swirl 
This patch fixes SMP booting:
Entering SMP Mode...
Starting CPU 1 at f01e46e4
Calibrating delay loop... 180.63 BogoMIPS
Starting CPU 2 at f01e46f0
Calibrating delay loop... 181.86 BogoMIPS
Starting CPU 3 at f01e46fc
Calibrating delay loop... 182.68 BogoMIPS
Total of 4 Processors activated (721.71 BogoMIPS).

Though depending on version Linux usually hangs later.
