It took me some time to get kickstarts working too, but here's what
finally did it for me: 

kernel = "/boot/rhel5-amd64-ks-kernel.img"
ramdisk = "/boot/rhel5-amd64-ks-initrd.img"
extra = "selinux=0 ip=10.10.7.7 gateway=10.10.7.1 netmask=255.255.255.0
dns=dns,servers ks=http://path/to/kickstartfile ksdevice=eth0"
name = "hostnamehere"
memory = "512"
disk = [ 'tap:aio:/var/lib/xen/images/test2.img,hda,w', ]
vif = [ 'bridge=xenbr0', ]
vcpus=1
on_reboot = 'destroy'
on_crash = 'destroy'

Those kernel and initrd images come right out of the directories you're
talking about (although RHEL for me, the CentOS images work the same).
If you aren't hosting your ks over HTTP, I'm not sure how you'd do this
exactly, but you could always do so and set it up with the "interactive"
flag turned on, which should allow you to specify installation media.
