If you look on the GHC-on-ARM page[1], you'll find my attempts to 
bootstrap GHC 6.6 (the last version where cross-compiling GHC actually 
worked) to ARM.

The only success I had was in using jhc (not GHC) to generate portable 
C, which cross-compiled and ran fine (on my Nokia N810). GHC's C 
wouldn't compile out of the box, and I'm not sure what libraries or 
other hackery is required to make it do so.

Details of the failed cross-compilation and success with jhc are on the 
wiki page[1].

I'd love to have this working, but I have no time at all this term.
