Apple SSD and TRIM support in Lion?

I own a Macbook Pro (model 5.3 - mid 2009) - which was maxed out at the factory - 3.06 ghz processor - 8 gb ram and 250 gb SSD.

I recently upgraded the OS from 10.6.8 to 10.7.4 and was hoping that this would enable TRIM support for the Apple installed SSD (Apple SSD TS256A).

I was under the impression that TRIM support was enabled in OSX Lion for Apple branded SSD drives that are installed at the factory - yet when I check system profiler - it shows that TRIM is not supported.

So, my question is - what is up with this? Does this mean that the SSD does not support TRIM? And if so - is there anything I can do to help improve SSD performance by enabling TRIM or Garbage Collection? And if so - how does one go about doing this?

Thanks for any advice.
