I have a quadcore with 4 GB RAM loaded with K12LTSP 5EL 64-bit. We do
run into those issues with Flash being 32-bit only (crashes with
nspluginwrapper and 32-bit Flash under 64-bit Firefox, although you
can install 32-bit Firefox only) and no 64-bit Java browser plugin
being available. You should be able to use 16 GB RAM with the PAE
kernel on 32-bit Linux (up to 64 GB according to http://en.wikipedia.org/wiki/Physical_Address_Extension)
