Well, something else happens on my machine. X actually paint (modulo colors) on other virtual console than they should. Syncronization between X and kernel is lost. On tty1 I can see my windows (with messed colors and shifted, otherwise ok), but kernel apparently writes there. So if I type characters, pixels change.
If you look and X / console switch design, it is mess.
You are probably right with your diagnostics when machine freezes - I've seen those, also.
