Intel was pushing for a late November release of the final (bugfixed) version of their TRIM frimware for the X25-M G2.  It may be December 1st, but they came through.  The firmware can be downloaded HERE. My evaluation of the new firmware and the SSD Toolbox software can be found here, in the Storage section.

Note: the SSD Toolbox software (which enables performance monitoring and the ability to manually TRIM an X25-M G2 under Windows XP and Vista) is not yet available due to an issue with corrupted restore points.  More info here.

Intel X25-M G2 TRIM firmware is out, really, we mean it this time, honest! - Storage 2
