What's the setting of $TERM?

Framebuffer is irrelevant; it doesn't change how escape codes get
interpreted by the Linux tty driver.

So something must be different.  Either the $TERM setting (have you
perhaps changed it in your .bashrc?), or the terminfo database
(comparing 'infocmp linux' on the two installations might give a clue)
or in the kernel (which I'd find *very* surprising; those guys try hard
to maintain backwards compatibility for the userspace).

I'd try it on my laptop, but my text consoles are completely dead (first
Ctrl+Alt+F1 blinks and jumps back to X, the second one gives me a
completely blank blank screen.  I blame the 'intel' X.org driver.  Good
thing that I don't need text consoles any more.)
