My CPU is like that too:
processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Mobile Intel(R) Pentium(R) 4 - M CPU 2.00GHz stepping : 7 cpu MHz : 1994.259 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 3932.16
I also have an 'ht' flag -- but I've never tried SMP. XP doesn't seem to think HT is on here either, so I just put it down as an anomaly.
