Can an Operating System be written un C-unlike programming language

Continuing with the C debate, I have this question I want to pop in. I don't 
have much experience about developing Operating Systems, but I've read some 
of Operating Systems: Design and implementation. And some about Linux and 
whenever I look at an OS, it is a small piece of assembly (as small as 
possible) that prepares an environment where C compiled code can run. That C 
code relays heavily on the use of pointers and memory manipulation.
So, can an Operating System be written in a C-unlike programming language, 
like Slate ? If so, how would it look like ? I mean, a piece of asm to 
prepare an environment for C that prepares an environment for Slate, or is it 
possible to jump directly from asm to Slate ?
I'm not among those that say: "one language for each task" because I suffered 
from the fact that: "the web-application is built in PHP because it's good 
for that, the log analyzer in Perl because it's good for that, the inner 
loops in C because it's good for that and the desktop GUI in C++ and some 
toolkit because it's good for that. Now, we don't have a clue of how to put 
everything together and we are doomed".
So, how much of an OS can be written in a language like Slate ?
(I'm not asking what you want to do, I'm not starting a flamewar, I just want 
to know).
Thank you.
