But each package can use 2G as long as you have enough ram. On i386
you would be limited to 1GB or 4GB.

Also filesystem cache can use way more ram.

Several people already have voiced their wish to install a flash
plugin for mozilla. That would mean installing a 32bit i386 mozilla
even though we have a 64bit amd64 mozilla.

The need for choice is there. Your proposal would require mozilla for
amd64 to be renamed mozilla-amd64. And all plugins need to be changed
to have the right Build-Depends too. and so on for every other package
that needs the choice.

Not possible for sarge and not feasable for sarge+1 (since multiarch
will replace it the moment sarge is released anyway).
