Did this used to work before Flash Player 11.5?
According to the ActionScript docs, cacheAsBitmapMatrix is an AIR-only method.

property
cacheAsBitmapMatrix:Matrix
Language Version:
ActionScript 3.0
Runtime Versions:
AIR 2.0
If non-null, this Matrix object defines how a display object is rendered when cacheAsBitmap is set to true. The application uses this matrix as a transformation matrix that is applied when rendering the bitmap version of the display object.
AIR profile support: This feature is supported on mobile devices, but it is not supported on desktop operating systems. It also has limited support on AIR for TV devices. Specifically, on AIR for TV devices, supported transformations include scaling and translation, but not rotation and skewing. See AIR Profile Support for more information regarding API support across multiple profiles.
With cacheAsBitmapMatrix set, the application retains a cached bitmap image across various 2D transformations, including translation, rotation, and scaling. If the application uses hardware acceleration, the object will be stored in video memory as a texture. This allows the GPU to apply the supported transformations to the object. The GPU can perform these transformations faster than the CPU.
To use the hardware acceleration, set Rendering to GPU in the General tab of the iPhone Settings dialog box in Flash Professional CS5. Or set the renderModeproperty to gpu in the application descriptor file. Note that AIR for TV devices automatically use hardware acceleration if it is available.
For example, the following code sends an untransformed bitmap representation of the display object to the GPU:
