Another datapoint:
My pxeboot config file (named with the mac address of the machine and downloaded by tftp) looks like this:
default centos timeout 5 prompt 1 display msgs/boot.msg
label centos kernel CentOS4.3/x86_64/vmlinuz append initrd=CentOS4.3/x86_64/initrd.img ramdisk_size=7000 ksdevice=eth0 ks=http://192.168.0.7/network-install/ks.cfg.x86_64
If I change the three instances of x86_64 to i386 everything works perfectly and it installs the i386 version. I thought maybe my x86_64 kernel and initrd that I copies from disc1/images/pxeboot were corrupt but I just downloaded them again from http://mirror.centos.org/centos/4/os/x86_64/images/pxeboot/ and they md5sum the same.
