[coduo] 64-bit linux and cod/coduo servers, cod2

[Geoff Goas]

my apologies if that has been discussed already.

i'm looking into renting another server for when cod 2 comes out, and
i'm trying to weigh my options. i'm looking at either a P4 3.2GHZ or
an AMD 64 3200+. my question is this: are the linux binaries for cod
and coduo compatible with a 64-bit operating system such as Centos 64?
or should i request that a 32-bit OS be installed instead.

thanks for the help.
