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.

All Northwood CPUs have ht, but it's disabled and you cannot use it.
(except you have an "official" HT-CPU 8-) )
