For all that are interested.
I went ahead and built my kernel with Symetric Muliprocessing support enabled and didn't have a problem. However I didn't see another CPU show up and the results of dmesg said HyperThreading was disabled.
After some further research online with the P4M processor I determined that allthough the flag "ht" was in my /proc/cpuinfo the chip infact *does not* have support for hyperthreading.

My flags tell me that I have a hyperthreading capable processor, which is new to my knowledge. I am curious if the output is garunteed correct before I compile the dual-processor options in my kernel.

I've never heard of them being wrong, as for "guaranteed", not sure I'd go that far.
I'm pretty sure you're going to be enabling hyperthreading (HT), not SMP, but I could be wrong.
Keep your old kernel around, then add an additional entry for it to your bootloader. Then if something goes wrong you can fall back to that.
