You might want to try one of the Gentoo install disks. They have them
available for multiple architectures, including Sparc. They're bootable,
and even if they don't contain the necessary utilities, I would think
they'd be easy enough to install. At least on x86, they can mount XFS
filesystems on a RAID setup.
