Comment(by tibbe):

 Replying to [comment:6 dterei]:
 > I don't really know without testing. What is the state of the 64bit
 version of GHC on OSX? Ben Lippmeier has graciously provided me with
 access to his OS X machine and I've been using this to do any testing and
 development. His machine seems to be running a 32bit kernel though
 (although its running 10.6 on Core i7 hardware). It seems though that I
 should be able to run a 64bit version of GHC on this still, correct?

 I'm running a 64-bit GHC with a 32-bit kernel and it works fine:
