Where it should not be, and you forced that support in without any
communication with the rest of the powerpc debian developpers.

Sure, i will. And once the biarch kernels are in, and we start to have ppc64
libraries and choice apps, they will move by themselves.

I have some unofficial numbers showing that the pure-64 approach represent a
performance hit of around 20% (8 minutes compared to 10 minutes or so for a
compilation run).

Well, indeed, but it would be easier to get this done if you pqrticipated. I
still have to investigate and see if it is easily possible to have 64bit
binaries link with 32bit libraries, which would be neat, but i fear this will
not be the case.

And yes, we aim at having ful biarch support for etch.

Let's first have a study of the way we are going to go, and the advantages and
inconveniences of each, and then, we can take a decision in full knowledge.

Still the aim for etch is biarch support, and not polluting random package
with ppc64 stuff we don't really want to have.
