osg::ClipPlane hasn't changed much since it was original implemented in pre 1.0 days, it's a very thin wrapper ontop of glClipPlane so that isn't much variation you can do when targetting the fixes function pipeline. What it sounds like is a drive bug on your system. As such I don't expect updating to OSG-3.0 or 3.2 will make much difference to this particular issue. There lots of other improvements on the OSG in 3.2 that are very much worthy of updating too so I'd recommend updating.
