You cannot rotate or freely rearrange the toolbars (e.g. place them on one row) - afaiu this is a limitiation of GTK+.
In Inkscape 0.48, you can now choose between three different arrangements (menu 'View' -> Default|Custom|Wide). [1]

If you detached some toolbars and then changed the arrangement while one of the toolbars is still floating, the floating toolbar might change the layout of the icons, but not resize. In such a case either close the toolbar with your window manager commands or open a new window: this will automatically reattach the toolbars in the proper locations.
