How can I check if I need to make the texture POT? Any glGetIntegerv() I can check?

Another problem I've encountered is when I switch back to my normal rendering the depth buffer is no longer working.

I have this code

Code:
if(m_textureRenderer->IsActive())
{
    glBindFramebufferOES(GL_FRAMEBUFFER_OES, m_textureRenderer->GetFrameBuffer());
    glBindRenderbufferOES(GL_RENDERBUFFER_OES, m_textureRenderer->GetDepthBuffer());
}
else
{
    glBindFramebufferOES(GL_FRAMEBUFFER_OES, m_defaultFramebuffer);
    glBindRenderbufferOES(GL_RENDERBUFFER_OES, m_depthRenderbuffer);
}

If I don't active the texture rendering then it renders fine, it's only when I go to texture rendering then back again that the depth buffer no longer works.
Looks like all I need is

Code:
if(m_textureRenderer->IsActive())
    glBindFramebufferOES(GL_FRAMEBUFFER_OES, m_textureRenderer->GetFrameBuffer());
else
    glBindFramebufferOES(GL_FRAMEBUFFER_OES, m_defaultFramebuffer);

And to restore the default depth buffer

Code:
glBindRenderbufferOES(GL_RENDERBUFFER_OES, m_depthRenderbuffer);
glFramebufferRenderbufferOES(GL_FRAMEBUFFER_OES, GL_DEPTH_ATTACHMENT_OES, GL_RENDERBUFFER_OES, m_depthRenderbuffer);
