SSD detected as HDD by OS X
I'm having some problems with a new SSD in a mid 09 1.86ghz macbook air.
I installed it and everything went ok until I checked for trim support (running 10.6.8), found out that Mac OS X has mistakenly identified the SSD as a conventional HDD and therefore won't enable trim. I did a clean install, smc and pram resets, even tried running Lion but I'm having the same problem. I know the SSD supports trim since I tried with Windows 7 on bootcamp and it reports it as enabled.
This is what System Profiler reports of the SSD (it's an apple toshiba unit)
NVidia MCP79 AHCI:
Product: MCP79 AHCI

Negotiated Link Speed: 1.5 Gigabit

Is there any way of fixing this?
