zfs discuss - Dec 2011 - SUNWsmbs & SUNWsmbskr for Sparc OSOL snv_134?

Does anyone know where I can still find the SUNWsmbs and SUNWsmbskr 
packages for the Sparc version of OpenSolaris? I wanted to experiment with 
ZFS/CIFS on my Sparc server but the ZFS share command fails with:

 	zfs set sharesmb=on tank1/windows
 	cannot share ''tank1/windows'': smb add share failed

modinfo reports that the nsmb driver is loaded but I think smbsrv also 
needs to be loaded.

The available documentation suggests that SUNWsmbs and SUNWsmbskr need to 
be installed. My system has SUNWsmbfskr installed and according to pkginfo 
this provides ''SMB/CIFS File System client support (Kernel)'' -
is this the
same package as SUNWsmbskr?

Thanks in adavnce for any suggestions,

Andy
