I've looked high and low, but haven't been able to find data concerning how much power a typical WUXGA screen (ie: like my SEC3225 Samsung panel) consumes in the 15.4" form factor.

Another question I have to laptop display gurus -- are the backlights on WUXGA screens stronger than on WXGA or WSXGA+ screens, to overcome the higher degree of light attenuation that is present in such screens?

Just trying to calculate the 'theoretical' impact of my WUXGA screen on my laptop and its 85Wh battery. Was thinking of going with a SSD to improve battery life, but after doing the math -- a SSD would only improve things by 5-10%, at best, and would practically cost as much as simply getting a laptop with a more efficient screen.

The screen type and backlight are two very different parts with different technologies. I don't believe the screen type to make the much of a difference since it is still the same sized screen in the end, though changing the backlight from CCFL to LED will make a bit of a difference. I doubt you get more than 10% battery life, like the SSD, but usually upgrading the backlight is cheaper than the SSD.
