First of all I am not sure if this is the right place. I am not familiar with this web based forums (i miss a set of mailing lists for Zaurus on different topics) anyway...
I was missing locate command on Z. So I cross-compiled slocate package against arm and tested it on sl-5600 with tckrom. it works well.
it is awailable at http://www.killefiz.de/zaurus/showdetail.php?app=1769.
