I'm sorry, since I work in a pretty restricted area, I can not offer
webspace-similar download areas, but if it is not offending the list, i could
provide a compressed output.

Find the output attached xz-compressed ... I cleared intentionally the serial
number, just as a notice.

I just checked this moment again, but the latest UEFI firmware Fujitsu is
offering is version 1.8.0 from April of this year.

On another machine, also Fujitsu, but a 19 inch rack server module with a low
energy XEON E5-12XXv3, I can clearly see the AESNI feature in Feature2 list
and, conclusively, the aesni0 device is present and reported.

I applied the port sysutils/cpuid to another system, runnin a i5-4200M mobile
CPU (Lenovo notebook). The rows indicating

family          = Intel ...
(simple synth)  = ...

look much more "modern" for my opinion as the output I provided shows on the
CPU in question. It is just a hunch ... Seems, I've bought Intel(ian) crap ;-)
with no features and from another mellenium ...

oh
