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.
