In what way? > Is there work being done to make this smoother? [...] Debian users are now generally installing a full amd64 (userland and kernel installation. The default installation image linked from www.debian.org is the 32/64-bit net-installer which will install amd64 if the system is capable of it. Based on your experience I might propose to change the automatic kernel selection for i386 so that we use 'amd64' on a system with >16GB RAM and a capable processor.
