On the other hand, Oracle uses tmpfs pseudo-files as "memory banks", you can split your memory in chunks and map whichever you need to access at one time. 16+ GB SGA was never a problem on 32-bit Linux, even in times of Oracle 9i and "kernel-hugemem" and stuff. And no, it wasn't slow.
So yeah, I run i686/PAE system at home, run VMs and stuff on it and see no reason to upgrade to x64. Maybe one day an application will appear that will force me to switch, but so far nothing on the horizon.
