If you read the other thread properly you'd see that the BIOS has 
an option to enable or disable it... when enabled it shows up.

NX is detected ok on the C7:

processor       : 0
vendor_id       : CentaurHauls
cpu family      : 6
model           : 10
model name      : VIA Esther processor 1500MHz
stepping        : 9
cpu MHz         : 800.000
cache size      : 128 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 1
wp              : yes
flags           : fpu vme de pse tsc msr pae mce apic sep mtrr pge cmov pat clflush acpi mmx fxsr sse sse2 tm nx pni est tm2 rng rng_en ace ace_en ace2 ace2_en phe phe_en pmm pmm_en
bogomips        : 1601.18
clflush size    : 64

I can't reboot that box just to test cx8 detection (which is missing).
