UEFI support in bhyve (Solaris VM possible?)

What is the status of UEFI support for bhyve in FreeBSD-10.3-RELEASE? I am looking to run a Solaris VM and I believe this (UEFI) is the only way it can be done.

I think I remember there was some rudimentary support for UEFI now.

Ah, here it is: PR 295124. It mentions SmartOS, which I believe is based on (open)Solaris. Not sure if it's meant as a hypervisor or guest. You would probably need to update to 10-STABLE though.
