I've been using a batch macro as you see in the code below to re-create my toolbars. If you look in vusrdefs.e and search for def_toolbartab, you'll see where it stores your toolbar info. If you look in tbprops.e, at the ctlnew.lbutton_up() function, you'll see code that does a similar thing with def_toolbartab. To execute a batch macro, you just type it's name on the slick command line - you don't prefix it with "load". To get vusrdefs.e updated, you have to change some other configuration setting - possibly calling _config_modify_flags in the batch macro would save having to do that but I've never bothered.
Normally I would let slick create my toolbars just by running vusrdefs.e from an existing configuration, but due to a limit of approx 1048 characters in the def_macfiles string in vusrdefs.e, I usually manually edit vusrdefs.e and assign an empty string to def_macfiles, which means my toolbars don't get created because the associated forms don't exist. Hence I load all my macros and toolbars "manually". Slick 2009 has an export options feature but it doesn't look like it includes toolbars - also, in slick 2009 release version, it currently doesn't work because it creates an invalid zip file for some reason.
