Booting from freebsd-boot on gpt using zfs root on mbr

[Bruce Cran]

Hi,

I'm trying to boot from gpt but with the zfs root on a mbr disk so I
can avoid overwriting the mbr bootcode on ada0.  The
layout is:

ada0s4: freebsd-zfs 80 GB (zroot)
ada1p1: freebsd-boot 128 kB

When I enter "zroot:/boot/kernel/kernel" at the boot: prompt I get a
register dump followed by "BTX halted". Is there some way to get this
configuration to work?
