This worked for me, though that was quite a while ago. Presumably it 
still works. I don't remember doing any magic, just using the Maemo 
cross-compiler to build the output of jhc.

The only annoying part was having to build with jhc outside the 
scratchbox environment and then build the C output inside the 
scratchbox. This is necessary because jhc is not self-hosting and I 
couldn't get GHC to build for Maemo.

The attempts to build GHC (back in the 6.8.2 days -- supposed 
cross-platform bootstrapping works again in 6.12, maybe it'll work now) 
and the success with JHC are documented at [1]. Actually, I just looked 
and Dustin Weese succeeded where I had failed, and got an unregisterized 
6.8 to bootstrap to Maemo.

I've since learned ARM(v4) assembly for an embedded systems course, I 
might look into writing a properly registerized ARM back-end for GHC 
6.12, now that the back-end overhaul is complete. That's definitely a 
Copious Free Time project, since I don't intend to be doing any ARM dev 
in Haskell or otherwise.
