Biarch can be usefull because is many cases the drawbacks of 64-bits
(bigger datatypes, including bigger pointers, which lead to an
increase of memory bandwidth and cache-line usage) are more important
that the gains. I don't know exactly for AMD64, but for Sparc 64, many
applications run faster when compiled in 32-bits.
But that's not a reason to delay AMD64 from being in Sid IMHO. It's
just a reason for why biarch would be good on the long run.
