As of QGIS 1.7.3, there doesn't appear to be any way to reverse the direction of a linestring (or linear ring).
LINESTRING (140 350, 220 340, 230 370, 280 370, 280 300, 210 260)
LINESTRING (210 260, 280 300, 280 370, 230 370, 220 340, 140 350)

I wrote a small plugin to do this a while ago, can be found in the Plugin Installer searching for "Swap". I plan on adding this function to the core QGIS code at some stage but no ETA at the moment.
