You might try removing this chunk of code in radeon_atom_mode_fixup()
in atombios_encoders.c

        /* hw bug */
        if ((mode->flags & DRM_MODE_FLAG_INTERLACE)
            && (mode->crtc_vsync_start < (mode->crtc_vdisplay + 2)))
                adjusted_mode->crtc_vsync_start =
adjusted_mode->crtc_vdisplay + 2;
