If I could have loaded tmpfs it would have. But the tmpfs.ko module was not
being built so it couldn't be loaded. I wound up cding into
/usr/src/sys/modules/tmpfs and running make and make install to build and
install it. After that kldload tmpfs did work.

For some reason it isn't getting built on the system. Not when the kernel
or world are built.
