[Paparazzi-devel] Paparazzi 3 - IMU Hardware, suggestions?

I noticed from the CVS codebase that paparazzi 3 has the capability of using some IMU hardware, but I couldn't find specifics on how this hardware is configured or if there are specific manufacturers. Any sneak-previews of the paparazzi III hardware? I'm working on some arm/atmel based avionics, and would like to make it as cross-paparazzi like as possible, and possibly incorporate better sensors. (I'm worried the hilly terrain might cause problems for the thermopile sensors). Has anybody used the analog devices accellerometers to build an IMU? Obviously, I would still need gyro's, which seem pricy. Any budget IMU solutions? Any benefit to having 2 axis accelleromters without gyros in trying to build a control algorothim? I'd guess not, since they really only tell part of the picture.
