Following up myself, I had a discussion with maintainer of pst-pdf and
it seems that it is not easy to make preview support recent luatex
natively. Hence, I added the following line to preview.dtx:
\IfFileExists{luatex85.sty}{\RequirePackage{luatex85}}{}
Emmanuel, do you have a chance to install the latest preview from AUCTeX
git and give it roll?
TIA, Arash
