The pdftex primitives not in luatex are all rather obscure for your  
purposes, I'd imagine; things like \pdfelapsedtime, \pdfmdfivesum,  
\pdffilemoddate, ... Probably the most useful one is \pdfstrcmp.

You can look to Heiko Oberdiek's pdftexcmds, which will work under  
plain, to resolve the interface differences between pdfTeX and LuaTeX  
(as well as XeTeX, incidentally). Beyond that package, I think you'd  
experience mostly smooth sailing between the engines, although you  
should never expect identical output between them.
