As we discussed yesterday, a 64bit build would benefit only users that 
install the disk into a hard drive. Almost all systems today are 64bit 
and support >4GB RAM. So it would be nice to support those 
installations, and I have seen a few around...

I agree that it is not worth the effort from the live disk perspective.

I suggest to make a test build at some point and see what works (the way 
chroot method also started)

I also had in mind that bringing in 32bit compatibility packages would 
kill us space-wise...
