XFS on SLES9

Hello, I would like to use XFS on Power at least for data partitions. For some reason XFS is not included in the file system list in Yast, I also did not managed to use it in autoyast. After the installation of the xfs-utils it was easy to format a logical volume with xfs on command line. What is the reason, for not including XFS in the Yast? Are there some known issues about using XFS on Power? Is it supported? Tomas Baublys
