It'll be on the (just released) IBM LC machines (the ones with the AMI
BMC) and will be in the next major firmware version for FSP based
machines (the -L machines) FW840, which should be out in the next
month. Let me know if you want a build of that, we should be able to get
one to you.

For any OpenPower machine you can always build a custom skiboot and
flash it :)
