The interesting part is:

Code:

glGetFloatv( GL_PROJECTION_MATRIX, mp );
      glGetFloatv( GL_MODELVIEW_MATRIX, mv );
      glMatrixMode( GL_TEXTURE );
      glPushMatrix();
      glLoadIdentity();
      glTranslatef (0.5, 0.5, 0.5);
      glScalef (0.5, 0.5, 0.5);
      glMultMatrixf(mp);
      glMultMatrixf(mv);
      glGetFloatv(GL_TEXTURE_MATRIX, clipmat);
      glPopMatrix();
      glMatrixMode( GL_MODELVIEW );
      glActiveTexture(GL_TEXTURE4+i);
      glMatrixMode( GL_TEXTURE );
      glLoadMatrixf(clipmat);
      glMatrixMode( GL_MODELVIEW );
      glActiveTexture(GL_TEXTURE0);

I could be that we are trying to access texture units beyond GL_MAX_TEXTURE_UNITS. Can you post your glxinfo.
