Right, but the Marvell driver doesn't. Here's the best description I found.
Marvell 9128 - Revisited (briefly)
The response they got from Gigbayte was this: "Marvel SE9128 controller can support TRIM command only with Win7 built-in driver, however, Win7 built-in driver doesn’t support SATA hot plug. With Marvell’s own driver, it doesn’t support TRIM command, but it enables hot plug."
I don't swear by any of this. Lot's of confusion about it. But the above is closest to the "real" answer I've seen.
