Did you test non-GPT booting? You updated BOOT2SIZE in its Makefile but
ignored the comment:
# We currently allow 32768 bytes for zfsboot - in practice it could be
# any size up to 3.5Mb but keeping it fixed size simplifies zfsldr.
#
BOOT2SIZE= 65536
If you want to use a larger size, you have to change zfsldr.S as it has a
hardcoded sector count that it loads off of disk:
.set NSECT,0x40
...
main.5: mov %dx,MEM_ARG # Save args
movb $NSECT,%dh # Sector count
movl $1024,%eax # Offset to boot2
callw nread.1 # Read disk
Since 0x40 * 512 = 32k, zfsldr.S is only going to load the first 32k of
zfsboot into RAM. If you need to bump this size up, you need to update the
comment and NSECT in zfsldr.S.
