The kickstart file is read by Linux, not pxelinux.  And it is read
using NFS or HTTP, not TFTP.  See:

    http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/custom-guide/s1-kickstart2-startinginstall.html

So you need to put your kickstart file on an NFS or HTTP server and
specify the full path to it in the ks=... option.  That should do it.

(Side note: The boot-time kernel options are available from
/proc/cmdline.  So, for example, if you would like to set the hostname
in the %pre or %post sections of ks.cfg, you can use sed or perl to
slurp out a "hostname=" option provided at boot time.  My approach is
to use a fixed hostname in the "network ..." directive, then do a
search&replace on it in the %post section.)
