Default No /proc/sys/vm/nr_hugepages

Is there a way to patch this box to enable hugepages?

# uname -a
Linux xxxxxx 2.6.18-53.el5xen #1 SMP Sat Nov 10 18:42:28 EST 2007 i686 i686 i386 GNU/Linux
# cat /etc/redhat-release
Enterprise Linux Enterprise Linux Server release 5.1 (Carthage)
# ls -l /proc/sys/vm/*huge*
ls: /proc/sys/vm/*huge*: No such file or directory
# sysctl vm.nr_hugepages=10
error: "vm.nr_hugepages" is an unknown key

For those interested, I solved my problem by installing and configuring kernel. Details at
