It depends on which LISP machine you're talking about, but I believe that 
in the case of things like the Symbolics and Explorer systems, that's not 
true: it was lisp all the way down to a kernel written in machine code 
and compiled by the same lisp compiler as the rest of the system.  Since 
these lisp systems operated on a holistic stored memory image model 
you're only a couple of reboots away from self hosting.  Also, they 
tended to be single-user systems without hardware memory protection (the 
LISP type system caught stray accesses).

So, while the LISP machines did have (actually, "were") an OS, and did 
all of the interrupt handling and device driving that other CPUs do, they 
didn't do it by running on top of Unix or whatever.  Somewhat like '80's 
vintage BASIC PCs in that regard.

Cheers,
