Sidebar is just classification, naming, categorisation.
Ignore it totally, dont use it and insert columns how you want, where you want. Imagine those 2 columns are called "Left sidebar" and "Right sidebar". Browsers dont care about your sidebars and how do you call your blocks.
You can insert in them WP Widget controls, cant you ?
You can even insert Primary, Secondary areas in columns on all places in template. WordPress, dont know how it is done for other CMS.
