You want your root partition to be RAID-1 (straight mirroring), because
the OBP and bootloader don't know about RAID.  Once the root partition is
mounted (and assuming that all of the bits you need for RAID support are
in the root partition, which is standard) you can mount other partitions
any way you like.  Remember, software RAID on Solaris operates on
partitions (slices), not whole disks.

RAID-5 with only two drives is silly, of course.  You could have 
additional drives in the same RAID-5 set for, say, /usr, but that is kind 
of a weird layout.
