Wow! That looks really impressive! Unfortunately on Debian/ARM I'll need 
to calm down your enthusiasm with 7.4.2 and TH, since I think we're 
still not there. Well, yes, GHCi is enabled as Ben Gamari provided truly 
fantastic work on writing GHC linker support for ARM, but I still see a 
lot of GHCi failures in GHC testsuite and also I'm not able to compile 
GHC to the end as always linker crashes while compiling some dph 
package. That's also the reason why I've finally found some energy to 
get GHC builder running again on my i.MX53, although this board is slow 
in comparison with current ARM state-of-the art CPUs, still if we see 
one or two GHC build failures on ARM per week perhaps some of us or 
others developers will find some energy to investigate the latest 
missing bits from ghc arm linker support and fix that. :-)

Thanks,
Karel
