It's patches the KEXT to support any SSD drive, not just the ones that come in the Apple MBP's. The catch is that your drive has to support TRIM, and apparently from what I can find, not all SSD's do. If you patch for a drive that doesn't have TRIM, things can go south.
Secondly, if you've used your drive a lot, it takes a while for the TRIM to work it's magic (sort like a defragger from what I read). One person said it took a couple of days.
I'm testing the patch but I cloned my boot drive onto yet another SSD. I checked the drive with Apples Profiler and it says that TRIM is supported after I ran the patch. Be aware that I wouldn't do this with an SSD that you're using in a production system. I'm using a spare drive and if it calfs, easy to restore the regular driver and go back (the patching utility has a backup and restore function in it).

If you choose to try the patch, the utility will report repairing "permissions" and before it's done that task, you might see a "patch applied...reboot" dialog. Ignore it until the permissions are repaired (the spinning wheel stops and reports it's done).
So far, so good. If I come across anything ugly, I'll post for sure.
As a caveat, I'll say that sometimes being on the bleeding edge of technology just means you need a really good supply of bandaids...
