Keep in mind that you don't always need 64 bit just because you have
more than 4 GB of memory. You can use a 32-bit "-bigmem" kernel in some
cases.
Using a -bigmem kernel means that all the processes together can use the
entire RAM, but each individual process can only access between 3-4 GB.
That may not be sufficient if you're running a huge database that
requires lots of memory dedicated to a single MySQL process, for
example, but it does work if you're using the RAM for lots of smaller
processes (such as a server running zillions of Apache processes or
POP/IMAP/SMTP processes).
