Yes, you understood my question exactly, thanks for expanding upon it.

Oh no, I'm almost done tuning my install, not more possible options to 
have to explore ;).

Hmm, if I understand you correctly, you are recommending using a 
non-illumos tool to create a Solaris MBR partition aligned on an 
arbitrary sector rather than a cylinder, which would then allow the 
beginning of slice zero in that partition to be in the right place? I 
didn't think of that, that seems much simpler than trying to calculate a 
cylinder offset of the slice relative to the beginning of the partition 
that lines up.

Thanks much…
