The new firmware is out and looks promising:

########## Begin SSD TRIM output ##########
word21 bit10 = 1: support for the DATA SET MANAGEMENT is changeable.
word169 bit0 = 1: device supports the Trim bit of DATA SET MANAGEMENT command.
word69 bit14 = 1: Trim function of the DATA SET MANAGEMENT command supports determinate behavior.
########## End SSD TRIM output ##########

This is the output from a modified hdparm, that checks the relevant bits.
..

I'll release hdparm-9.14 shortly, with reporting for the TRIM feature in the -I output.

Cheers
