Didn't it work as advertised?  It should.

See http://syslinux.zytor.com/archives/2007-April/008308.html for a
patch that does what you need (if I understand it correctly).
Basically, it lets you use macros in the kernel command line, which
expand to values read from the DHCP packet.  So in your pxelinux
config file you would write something like

label example
  linux vmlinuz-2.6.18
  append ip=$YIADDR$ gateway=$ROUTERS$ netmask=$MASK$ dns=$DNS$

In the previous you can find another path, which probably does almost
the same.  My patch is against 3.50-pre2, by I'd expect it to apply to
the current 3.50 release candidate.  If it does not, I'm willing to
shake it into form.
