Based purely on what I have observed, as opposed to standards, claims, or 
official pronouncements (which may be more correct), if you can boot Linux now 
you do not have a UEFI enabled system.

I have seen claims that FC18 will boot on UEFI, based on a sample size of one 
and Live-CD (x86_64) booting off a USB thumb drive, that is not the case. It 
seems that UEFI is not required to recognize the token MS sold Linux, so some don't.

If UEFI is active you can't run dmidecode, so the question may boil down to if 
anything shows when UEFI is present but not enabled, like SElinux in advicory mode.
