Problems with Radeon 9700

When I turn on VertexArray and EdgeFlagArray, and use DrawArrays function, all edges are visible, even edges with turned off edgeflag. But if I use several functions ArrayElement its all right. Ofcourse I drawing polygon and use glPoligonMode(GL_FRONT_AND_BACK,GL_LINE). On GeForce 2 GTS its works perfectly.
Help Please?
