Kernel + bigmem

Hello:

We updated the kernel on a server yesterday to the 2.4.20-31.9 kernel but when the machine came back we only saw 900MB of RAM being used, while the server has 2GB of RAM.

We have installed the bigmem version of this kernel and rebooted the server but we are still seeing 900MB of RAM. We think the kernel hasn't been updated correctly.

Does anybody see anything strange in the grub.conf file causing the kernel not to update to the bigmem version?

Code: 
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/sda2
#          initrd /initrd-version.img
#boot=/dev/sda

When we do uname -a we see the following:

Thanks in advance Kernel + bigmem
