Ubuntu :: Startup Tty1 Instead Of X Console?

I want to use Ubuntu to build an information terminal. This will basically be an X application that displays interesting information. I has to be lightweight seeing that it is installed on compact flash memory.I started with a 10.04 command line install and added xserver-xorg. Please note I am not using a window manager or desktop environment; bare bones X only. I have created a /etc/init.d/myapp file which can start my application by calling "/usr/bin/xinit ${MYAPP}". I used update-rc.d to create a symlink in rc2.d that points to /etc/init.d/myapp. Here is my problem:

On startup the application runs but the system sometimes switches to tty1 (virtual console 1) instead of displaying the X console. I then have to manually switch to it by pressing Ctrl-Alt-F7. How can I make it *always* display the X console with my application? Another thing I noticed is sometimes the X server runs on virtual console 7 and other times on 8. I though that X starts on the first available console and Ubuntu has 6 ttys configured by default. So I would expect it to always run on 7, like and ordinary Ubuntu desktop.
