Thanks. That gave me shutdown and reboot.. but fast user switching is gone.
I was able to edit /etc/kde/kdm/Xservers to:
:0 local /usr/X11R6/bin/X :0 vt7
:1 local /usr/X11R6/bin/X :1 vt8
:2 local /usr/X11R6/bin/X :2 vt9
:3 local /usr/X11R6/bin/X :3 vt10
:4 local /usr/X11R6/bin/X :4 vt11
:5 local /usr/X11R6/bin/X :5 vt12
:6 local /usr/X11R6/bin/X :6 vt13
... That gave me the abilty to "startx -- :1" etc to get another desktop (for who's logged in the shell at the time), then I can ctrl-alt-Fx around but still not perfect. I think it's 'cause they're perm, not reseved... will dig more...
Oh, about the "looks like gnome" thing... even when kde and gnome are themed the same.. etc.. I can tell the difference. Maybe in the rendering, or palette or something, but it has a different look/feel.
I tried every version of reserve I could think of... no dice.
