On this server I have: CentOS release 4.6 (Final)


In the discussion at the centos site   that you mention it seems more of a 
problem with Centos 5.
http://www.centos.org:80/modules/newbb/viewtopic.php?topic_id=8457

On my servers when Lilo accidentally puts a non-smp kernel in place, then I 
only see 3 gigs.
So 2.6.9-67.0.7.ELsmp shows the full ram but  2.6.9-67.0.7.EL does not.

According to:
http://www.linuxtopia.org/online_books/centos_linux_guides/centos_enterprise_linux_sysadmin_guide/ch-kernel.html

kernel-smp - Contains the kernel for multi-processor systems. The following 
are the key features:


  a.. Multi-processor support

  b.. Support for more than 4 GB of RAM (up to 16 GB for x86)

  c.. PAE (Physical Address Extension) or 3 level paging on x86 processors 
that support PAE
