I'll post something I heard about when looking into upgrading Oracle 8i
from Windows to Oracle 10g on Linux.
To get more memory for the process, you would enable big memory page,
and then create an in-memory temp file system; you could then allocate
extra memory for a process, and part of it would be swapped out to this
temp file system in memory. Red Hat Advanced Server was the OS of choice
for those who did it - I played around with it, but couldn't get Oracle
to start with larger memory settings (we weren't running on RedHat AS).
Maybe you'll have more luck.
A good page that talked about this was,

Good luck.

It has nothing to do with linux.. its an x86 thing.. So no..
However, some kernels have things to let you go over, but you get weird
results when doing so.
