What is the output of /proc/cpuinfo? If this is a really new machine it 
is possible that we don't have the information coded to recognize the 
really new processor and the machine falls back on the timer mechanism. 
The other possibility is that this is a UP kernel and the APIC support 
is not compiled in.
