Does it actually boot via a UEFI, or did UEFI fall back to CSM
and do a legacy boot?

What does "sysctl machdep.bootmethod" say?
machdep.bootmethod: BIOS

The .iso building was updated to create hybrid boot images some
time back, these .iso images should be usable as boot .iso on a
cd/dvd and as memstick images.  I would encourage there use over
the memstick images, as there is a plan to remove them once we
get better experience with the hybrid .iso.

It is also possible that something has munged the boot in head.
Have you tried a downloaed ^/head snapshot from the last week,
as it could also be your build system that is not producing
a proper boot image?
