ive always used `emerge nvidia-kernel nvidia-glx` to take care of my nvidia
card on my x86 and amd64 machines ... then just put 'nvidia'

i'm not really up-to-speed with how fedora/redhat/suse/debian/etc... are
handling the multilib issue, but i can speak for Gentoo ...
since it sounds like you're doing a new install, grab a 2005.0 amd64 install
and the rest should be pretty seamless ... with the 2005.0 release, amd64
supports multilib by default (you can turn it off if you wish to have a pure
the default glibc/gcc will install 32bit and 64bit compilers / libraries ...
just make sure you turn on 32bit emulation support in your kernel, and then
when you go to run a 32bit app, most will 'just work' ... of course it
depends on *what* you're trying to do as to how easy it'll be
if you wish to compile your own 32bit code, just add '-m32' to the build
gcc -m32 -c test.c -o test32bit
