I have a western digital drive with 4k physical sectors that causes OpenIndiana to use ashift=12 (and refuse to use it as a replacement in an ashift=9 vdev), though it appears to report 512 logical sectors, so somehow OpenIndiana noticed the real sector size. It is model WD30EURS (a green "AV-GP" drive). Is it close enough to what you want for solaris to know that it is really 4k, even if it is a 512e drive? Some smartctl info: Device Model: WDC WD30EURS-63R8UY0 ... Firmware Version: 80.00A80 ... Sector Sizes: 512 bytes logical, 4096 bytes physical hdparm -I (on linux) also figures out that the drive has 4k physical sectors.
