here's my ultra-l337 startkde scriptset for anyone who's seriously bored :)

the xinit script is a "replacement" for xdm in gentoo's init.d directory,
thus making kde auto-login as your user without needing kdm (as it really 
slows down startup :( ). the xinit script as can be seen runs another xinit
script in my path in a delayed fasion (telinit a, gentoo voodoo that works) 
then this su's and executes my actual .xinitrc script, which in turn calls 
a special (my)startkde. following me still?, think i can get it faster, 
but i can't really be arsed atm as this works v. well.

hope that mail clients see the full path names :)

# This is here to serve as a note to myself, and future developers.
#
# Any Display manager (gdm,kdm,xdm) have the following problem:  if
# it is started before any getty, and no vt is specified, it will
# usually run on vt2.  When the getty on vt2 then starts, and the
# DM is already started, the getty will take control of the keyboard,
# leaving us with a "dead" keyboard.
#
# Resolution: add the following line to /etc/inittab
#
#  x:a:once:/etc/X11/startDM.sh
#
# and have /etc/X11/startDM.sh start the DM in daemon mode if
# a lock is present (with the info of what DM should be started),
# else just fall through.
#
# How this basically works, is the "a" runlevel is a additional
# runlevel that you can use to fork processes with init, but the
# runlevel never gets changed to this runlevel.  Along with the "a"
# runlevel, the "once" key word means that startDM.sh will only be
# run when we specify it to run, thus eliminating respawning
# startDM.sh when "xdm" is not added to the default runleve, as was
# done previously.
#
# This script then just calls "tellinit a", and init will run
# /etc/X11/startDM.sh after the current runlevel completes (this
# script should only be added to the actual runlevel the user is
# using).
