Just done a greap of OSG master and it doesn't have glClearBufferData
so the answer for now is no.

Implementing in your own local code you could use a draw callback,
such as an osg::Camara pre/post DrawCallback.   The other approach
would be to add the function entry point into include/osg/GLExtensions
and add where it's appropriate to add the call into the OSG to be
conviniently support it.  I haven't yet looked at the specs of the
function so can only guess at where it might be supported.  Adding it
into the core OSG would mean it could be part of the up coming
