  Robert,

   what makes me wonder is SLES9 on this same hardware shows the 4Gb RAM,
and I already had installed all CentOS x86_64 pre-compiled kernels on this
machine without success. This little memory (150Mb) can't impact my application
but I'm always searching for it :)

   thanks,

        Antonio.
