Also on that page, why only bind-mount /usr/portage/distfiles, and not the full portage tree. This would save disk space nd server bandidth. 

Both of these work just fine on my sys.

sure, you can use -march=athlon64 in 32bit, but if you look at the source for gcc you will see it implies 64bit code generation. sometimes this breaks shit, even if it doesnt really generate 64bit code... so you would have to -mtune=athlon64 or "-march=athlon64 -m32" for it to work all the time. and even then, -m32 would occasionally be stripped by a few ebuilds...
