On a new computer, dmesg shows:

CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (2793.01-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0xf29  Stepping = 9
  Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
  Hyperthreading: 2 logical CPUs
acpi_cpu0: <CPU> port 0x530-0x537 on acpi0
acpi_cpu1: <CPU> port 0x530-0x537 on acpi0

Should options  SMP  and  APIC_IO  be enabled in kernel?
