Another tool that we demonstrated at the show was SpeedSwitchXP. It's not fully supportive of all the features of the Atom Processors, but was functional enough to enable and disable speedstep, and to force the processor/OS to change modes. You can download it at http://www.diefer.de/speedswitchxp/. YMMV (Your mileage may vary).. In particular when it was used in combo with Core-Temp or CPU-Z the readings seemed to be a bit off.
The final utility that you may find of interest is one that reads EDID (Extended Dsiplay Identification Data) structures from a connected display, and allows you to edit them. Its also a free download and you can get it at http://www.entechtaiwan.com/lib/softmccs.shtm
The screenshot is too big to show on this blog, but if you go to their website they have some decent pictures EnTech's website states "softMCCS is a purpose-built diagnostics and compliance application implemented on top of EnTech's next-generation, licensable softOSD communications library."
