Approx 35W more power usage in multi-screen

When using multiscreen on the radeon driver, dpm is disabled. This means the adapter draws approx 35W more power due to no dynamic power management.
While I would love to continue to use this card + radeon driver (which works perfectly in all other regards), the extra heat generated make this not an option.
Multi-monitor configs are becoming more and more common - but they are almost unusable power / heat wise.
While this is probably a pipe-dream - what are the chances of getting some form of power management that isn't just "severely cripple the card"?
