No. Actually, the reverse of that was one of the reasons why the Lisp Machines (http://en.wikipedia.org/wiki/Lisp_machine http://en.wikipedia.org/wiki/Lisp_machine) ultimately failed (among others): commodity hardware could run Lisp as fast or faster than custom hardware. Nowadays, the hardware doesn't limit the creation of a Lisp OS, but many other things do. 1) Getting people that want to do the work (http://linuxfinances.info/info/lisposes.html http://linuxfinances.info/info/lisposes.html) 2) The fact that you can run perfectly good Lisp implementations on top of general purpose OSs significantly decreases the need for a Lisp OS. 3) Lisp isn't as popular as it once was (or should be :) http://lists.tunes.org/mailman/listinfo/lispos/ http://lists.tunes.org/mailman/listinfo/lispos/
