  It does work, but you have to either edit the grub.conf on the install 
ISO and repack, or get in quick and edit the grub command line and add a 
'console=ttyS0' option.

  grub-bhyve auto-inserts the serial console line into the linux kernel 
boot options which is why it appears a little more seamless.

  UEFI does have the advantage that the system is self-consistent - any 
boot filesystem can be used, whereas grub-bhyve only understands the 
ones that are built into it.
