Yes this works. (But I don't like how it works.)

setup-storage will create a new partition and mark it and the location of this 
'boot'-partition is at the beginning of the disk, but the partition index is 
the next after the last defined partition, e.g.:

disk_config disk1 disklabel:gpt-bios
primary     /           200M      ext3  rw,errors=panic
primary     -           400M      swap  -

will result in

1) sda3 - biosboot
2) sda1 - /
3) sda2 - swap

Yes this is mostly a cosmetical issue. I can understand why it has been done 
this way. Still don't like 'out of order' partitioning. There's a workaround 
to achieve 'ordered' partitions.

disk_config disk1 disklabel:gpt
primary     -           1M        -     -
primary     /           200M      ext3  rw,errors=panic
primary     -           400M      swap  -

However you _must_ set the required flag manually after the partitioning has 
been done and before grub is being installed.

@Bob:

The reason why 'primary - 8  bios_grub' does not work is that setup-storage 
only provides 'filesystem creation'- and 'filesystem mount'-options. But this 
is not a filesystem issue. The required flag belongs to the partition layer.
