Regarding libc6 and sun4m:
I thought libc6-sparc64 existed for these kinds of optimizations.

Why not simply create a separate distribution for sparc32 and sparc64
then? Keep the sparc32 compatible while optimizing to your hearts content
for sparc64. I would really like to continue using my sun4m as a Debian
based web server instead of going back to Solaris.
