DPMS may not be implemented for flat panels, but something seems to be. I use a laptop with an ATI Radeon Mobility graphics adapter, with the internal flat panel and an external monitor set up to run simultaneously with Xinerama. I noticed in the last day or two that when the external monitor went into power-savin mode, within seconds, the internal flat panel also went blank and its backlight shut off.
