I've seen no comments from the lists. I've also posted it on the OCZ Forums, and gotten some users confirming it works there.

Well, when you put things like "NOT FOR COMMIT USE; TESTING ONLY; NO WARRANTY; DANGER!" and "I constructed this patch for my friend to test, completely blind. I haven't heard back from him at all yet, but I thought that the wider community might find it useful for testing as well. I think it _should_ work, just need to figure out what the correct chip variant is." On the patch it tends to make maintainers exercise extreme caution. Thus comments from others (preferably successful test reports) or acks from Marvell or Vertex would be very helpful.

Both of those were on the first version of the patch, when I'd written the code and not run it at all. After that, I got access to a RevoDrive3 remotely, and run about 5TiB of data through it for testing. The second version of the patch removed those warnings, and described some of my testing: http://thread.gmane.org/gmane.linux.kernel/1200731/focus=50312 Some fio performance numbers: http://paste.pocoo.org/show/489716/ dmesg/hdparm/smartctl: http://www.ocztechnologyforum.com/forum/showthread.php?95151-Linux-patch-support-for-RevoDrive3-RevoDrive3-X2-zDrive-R4&p=686054&viewfull=1#post686054
