xfree86 and mandrake 9.2 with kernel-secure

[netpython]

Hi,

I run a linux box on the latest "secure" kernel from mandrake which
includes grsecurity.My question is: what can i do to run xfree86 and
while being properly secured ? I stopped the x-server from listening on
port 6000, i only browse the web and go on a variety of irc servers,
however i would like to keep using kdevelop and qtdesigner.
