I don't think anyone is actively working on it. I think it shouldn't be
that much work once the i386 loader is resurrected. The i386 kernel just
needs to use the EFI memory map and I think the rest of it should generally
just work.

Lundberg, Johannes
hardware is one solution (I did).
I never did try FreeBSD on BayTrail but for running Linux on BayTrail I
used special built Grub that was 32bit but could load 64bit OS. Could this
kind of Grub boot a 64bit FreeBSD, I wonder?

get grub loading on a test platform (tablet, for display etc) but didn't
manage to make it boot anything

work. OTOH, in the non-UEFI case we use an i386 loader that boots an
amd64 kernel, so it isn't impossible.

Yeah and it sucks. All to adapt to Microsoft who couldn't make 64bit UEFI
boot loader in time (or so I heard)...
I heard though that newer (Linux) versions of Intel Compute Stick would
have 64bit UEFI but I'm not sure.

This page contains some instructions and a downloadable booti32.efi image
that you can put in the EFI folder. That will boot a 64bit grub that should
be able to boot a 64bit OS.
http://liliputing.com/2013/10/booting-ubuntu-asus-transformer-book-t100.html
I do have customized Arch Linux memstick image with Grub and this
booti32.efi image so it boots on these systems. This can be used to install
a Grub bootloader that maybe can boot FreeBSD.
One question is, would Grub's filesystem drivers for FreeBSD work in this
mode?
Maybe I should give it a shot today..

That's great. However, as for all other BayTrail devices out there that
does not support Linux officially I think you're stuck with 32bit.

you have the Windows or Linux version. (The difference between the is the
amount of RAM and onboard storage, the firmware is the same)
I have the Windows one and it boots 64 bit just fine.
You can select it in the settings. (OS setting: Windows=32 bit, Linux=64 bit)

UEFI, grub (and therefore, linux) does it.
I think even openbsd at least has a 32bit loader, I'd settle for 32bit
but the problem is I can't easily boot it.
