the only companies i can think of doing that off the top of my head are some of the japanese ones like Ibanez with the 5-piece wizards (bolt-on and neck-thru) ESP Edwards line rockin the 9piece neck thrus which is somn i've only found on high end guitars-once again mainly japanese. like i said i'm only listing the ones i can think of right away and i'm pretty sure there's more...
Gibson Firebird V and VII are neck thru multilaminate construction.
Ovation has a multilaminate neck on all USA models, maybe some of the imports too (I haven't checked). For an acoustic, I gotta tell ya, that Ovation Adamas I've got... plays like a Strat (a Strat with .012's of course).
This pau ferro/ebony neck I found for cheap on eBay has a thin purpleheart laminate strip between the pau ferro and ebony board; you might be able to custom order something along those lines, call your friendly sales rep
