Yes. It's in Slackware 12.0
From slacke17 home page:

You need an official Linux Slackware 12.0 for x86. If you did install intrusive third party softwares and run into problems, do not complain. It was made for vanilla Slackware. On the other hand, you'd better to apply the security patch of the Slackware stable branch before installing SlackE17.
Wolvix is not vanilla slackware. And it's based on version 11.0
Try this one - for slackware 11.0 - seems to work in wolvix for me
