[CentOS] 32-bit boot CD for 64-bit install using kickstart

Hi,

I am using kickstart method for CentOS installation. The install is
done using mirror site URL and not CD/DVD ISOs. However, the system is
initially booted from 32-bit CentOS CD. When the install process
starts I get errors as:
- package rpm not found - abort/continue?
- package lvm2 not found - abort/continue?
- package grub not found - abort/continue?
- ...
- ...

If I change install URL to 32-bit ISOs then everything works fine. Do
I need to use 64-bit boot CD for this install?
