Corsair has recently published on his forum a firmware supporting the TRIM control of Windows 7 on SSD P64, P128 and P256, Samsung signed (clones PB22J). The update unfortunately loses all data on the flash disk. The bright side, the update seems to come directly from the Korean manufacturer, it could be compatible with all DSS architecture based RBB.

The new firmware, the VBM19C1Q, replaces the VBM18C1Q, which provided support for the BGC (Background Garbage Collection) and VBM1801Q the original firmware of Samsung PM800. Corsair offers a tool for updating (DSRD) and a user guide in a topic forum.
