Here's how I did my USB key (minus the kickstart part) but you need a linux (in a VM or from the live CD)...
And you will have to change devices names!
1. Create a small VFAT partition, then a big linux one:
fdisk /dev/sdg
Device Boot Start End Blocks Id System
/dev/sdg1 * 1 3 23126 6 FAT16
/dev/sdg2 4 1023 7873380 83 Linux
mkfs.vfat -n BOOT /dev/sdg1
mkfs.ext2 -m 0 -b 4096 -L DATA /dev/sdg2
Unplug/plug => /media/BOOT and /media/DATA
2. Install syslinux on the VFAT partition:
syslinux -s /dev/sdg1
cd /media/BOOT
cp -rv /mnt/cdrom/isolinux syslinux
mv syslinux/isolinux.cfg syslinux/syslinux.cfg
rm -f syslinux/isolinux.bin
vi syslinux/syslinux.cfg
append method=hd:sda2:/centos
3. Copy the CentOS ISOs to the linux partition (I had to use the CD ISOs because the DVD ones would get corrupt on my USB key for some reason):
mkdir /media/DATA/centos
for i in 1 2 3 4 5 6; do cp -v CentOS-5.3-i386-bin-${i}of6.iso /media/DATA/centos/; sync; done
for i in 1 2 3 4 5 6; do diff /IOL/CENTOS_repo/CentOS-5.3-i386-bin-${i}of6.iso /media/DATA/centos/CentOS-5.3-i386-bin-${i}of6.iso; done
4. Optionaly (?), to be sure that it boots:
dd if=/usr/share/syslinux/mbr.bin of=/dev/sdg
