No, you can't tell by looking at it.
There are two mistakes in your reasoning. One is that you're confusing two methods of attack: modifying an existing device, and making a device from scratch. The other is that your research clearly has an observation bias (presumably, because you're finding the things that are easier to find on the web).
Wedge attack was applicable on DDA cards (Dynamic Data Authentication) which were being superseded by CDA cards (Combined Data Authentication) at the time when vulnerability was disclosed.
The researchers behind the vulnerability proposed a solution to fix DDA cards in his write-up: Defending against wedge attacks in Chip & PIN but there's no track ...
Since the question is about the NI (New Instruction) set for AES, NI accelerates the the AES algorithm.
A right answer could be (also according to Intel docs):
cpuid | grep -i aes | sort | uniq
If you want to be sure, you can also try the following command:
sort -u /proc/crypto | grep module
This really gives the kernel modules that are loaded, which should ...
