Just flashed it to my stock Atrix and it works great! Used the Multitouch Vis Test app and before after 15 - 16 seconds the touchscreen would freekout now it's smooth and has the 5 points of touch. Sweet.....
My Atrix is rooted, BL Unlocked, and romracers recovery installed.
Edit: It maybe just the placebo affect, but the touch screen seem to respond better.
