thanks
yes, but with a little hack, i think
code ex. (demo theme) :
<!--[if lt IE 8]>
<style type="text/css" media="screen">#xo-canvas-leftcolumn {display: inline; zoom:1; width:180px;}
#xo-page {display: inline; zoom:1; width:462px;}
#xo-canvas.threecolumns-layout #xo-page { width:462px;}
#xo-canvas.leftcolumn-layout #xo-page, #xo-canvas.rightcolumn-layout #xo-page {width:810px;}
#xo-canvas-rightcolumn {display: inline; zoom:1; width:180px;}
</style><![endif]-->
