There should be an ANSI escape sequence for resetting the scroll region.
Just send that to the console.

Yup there is. It's Esc [r , however this also returns the cursor to the top of 
the screen. You can use Esc [s & Esc [u to save and restore the current 
cursor position, so it's just a matter of putting them around it thus:
 Esc [s Esc [r Esc [u

Or with echo (in a bash script - \\'s to escape it from the shell):
 echo -ne \\033[s\\033[r\\033[u

Now there is a problem with this solution: This leaves the logo (and any 
boot-time drawn graphics in the unscrollable region) on the screen.

Should it? :)
