Malbolge Unshackled (20-trit rotation variant), 3,2485e7 bytes
Size of this answer exceeds maximum postable program size (eh), so the code is located in my GitHub repository.
It's a slow monstrosity, but I love this one. The digits are being displayed in hexadecimal form.
Btw, the code is compressed using 7Zip and PPMd algorithm, because the program is plain too big to post to Github in it's state of art.
How to run this?
This might be a tricky part, because naive Haskell interpreter will take ages upon ages to run this. TIO has decent Malbogle Unshackled interpreter, but sadly I won't be able to use it (limitations).
The best one I could find is the fixed 20-trit rotation width variant, that performs very well.
To make the interpreter a bit faster, I've removed all the checks from Matthias Lutter's Malbolge Unshackled interpreter.
My modified version can run around 6,3% faster.

@PeterOlson Will there ever be an accepted answer to this question? – Gaffi – 2012-06-08T03:59:54.027
4@Gaffi Probably not, accepting an answer makes me feel like I'm ending the contest and discouraging new and possibly better answers. – Peter Olson – 2012-06-08T04:05:46.117
NB In a sense this is a simplified version of Distributing the balls
– Peter Taylor – 2011-10-21T11:03:31.367@Peter Olson: What's your opinion of ratchet freak's interpretation of "you may format it however you like"? If I followed his interpretation I could shave 18 characters. – Steven Rumbalski – 2011-10-21T20:57:51.890
@StevenRumbalski He's fine. There's a newline between each row, and there is a space between each number, so it meets the criteria. – Peter Olson – 2011-10-21T21:32:00.443
@Peter Olson: Thanks for the clarification. What about Tomas T's assumption that n is defined already? – Steven Rumbalski – 2011-10-21T21:50:14.837
