One thing I was wondering: Is there a proper way to make sure that 
acceses to the framebuffer end up only on one specific virtual console?
I have an application that runs on one virtual console, but when
switching I do not want the screen to be trashed by writing just into
the framebuffer memory. My solution was to check whether the current
console is the console the application started on, but this looks a
bit bloated to me and I had some weird effects when switching to X and
back - like one frame still got painted into graphics memory while X was
already shown.
  
  Any ideas?
