try adding modes to your screen configs, e.g.:

        Subsection "Display"
                Depth       16
                Modes       "1280x1024" "1024x768" "800x600" "640x480"
        EndSubsection

Also, I fixed HW cursor on crtc2, so you can remove the hwcursor "false" li=
ne.

here's a sample config:

Let me know if you still have trouble.
