Yeah well... I'm still to see significant performance benefits of 64
bits applications over 32 bits ones on my Sun Blade 100 at work.

True, but it's just a compiler flag, really, for the libraries. It works
well enough in Solaris. The kernel is a different issue that I won't
comment upon, mostly because I don't know much about it. :)
