Sorry... my question was partly answered by Jim Klimov on this list:

Apparently the currently-suggested way (at least in OpenIndiana) is to:
1) create a zpool on the 4k-native drive
2) zfs send | zfs receive the data
3) mirror back onto the non-4k drive

I can't test it at the moment on my setup - has anyone tested this to work?
