Silence your heretic anti-Debian libels! ;-) Comparing them to Gentoo,
indeed...

There is a Debian AMD64 / EM64T port, which will become official with the next
release (insert compulsory "some time in 2010" joke here).

Sorry for being unclear; I'm not talking about x86-64. AFAIK it is always a performance win to use 64-bit binaries on x86-64 because 32-bit x86 is so bad.

This is not at all the case with 64-bit PowerPC: it is usually a performance loss to simply recompile 32-bit binaries as 64-bit. Accordingly, only some initially misguided PowerPC distributions are 100% 64-bit.
