OK, thanks, I guess it's an AMD driver issue rather than a more generic drm thing then.
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;
