Julian Seward wrote some notes on the way GHCi works, which are in the 
commentary:

http://hackage.haskell.org/trac/ghc/wiki/Commentary/Compiler/Backends/GHCi

It's not much, but there are some technical details about stacks and 
suchlike there.  The bytecode itself is a pretty simple stack machine, I 
can probably answer questions if there's anything you need some help with.
