Site says it is only for 7 series chipsets, but there are reports of it working on others also (i.e. p67 and x58.) Note significant improvement on average write and read speeds with and without TRIM enabled, even after a format of the non TRIM enabled array.

Nice catch. After reading about it supporting drivers 11 and higher I had to go quickly check my driver numbers -- 11.5! Life is good.

Cool, I had heard this was coming. This is a game changer for the RAID users.
Main Server - WHS 2011, Core I5-2500, 12T RAID 5 (5x3T) + 2T of Mirror + 2T of backup
Second Server - 2008R2, Core I5-2500, 12T RAID 5
Main Systems - Core I7-2600k, 16 Gigs DDR3-1600, 180 Gig Intel 330 SSD Max IOPS 240 Gig Vertex 3, 2T Sata 3 for local Backup
Other systems - Core I7-2600, Core I3-530's, Core I5-2500, Core I7-920, Core I3-2100, and G620 (see System List)

RAID with TRIM = winning 
If at first you don't succeed, do it like your mother told you.

I tried these drivers a couple of weeks ago on my dev machine. And while it benchmarked very fast (two SATA6G Mushkin 256GB SSD in RAID0), it was not stable. In particular there was BSOD everytime on wake from sleep. On top of that, the difference was barely noticeable doing normal computing tasks and you have to pay a huge boot time penalty to have SATA In RAID mode (option ROM init). I played with it for a while, but then decided having my computer sleep properly was much more important than the extra performance. So, changed back to non-RAID0 MSAHCI drivers, and restored from backup.
I'll take a look at it again should they put out some new drivers/BIOS upgrade.

Oh, so it really is like Charlie Sheen's 'winning', illusory.

If there are issues waking up from sleep then there sounds like other problems. I know - big help. I agree with the extra time on boot from the RAID having to read the BIOS info, but I suppose it depends on how often you reboot if the speed or reliability (depending on 0/1/5) is worth it.
I'll tell you the speed of two SSDs in RAID 0 is no illusion.
