OK, see below.

Hmm, interesting - I did run 'make installer_release' as root, which I
assume should do everything (build+install world+kernel) as root. 
Possibly I didn't clean up enough before running it...

I'm using what [n]curses provides for detecting an ESC keypress, which
should work like you describe.

But ncurses' timeout may be longer than you were expecting.  Have you
tried pressing 'ESC' then waiting about a full second?  It works for me.

There may be a way to tell ncurses to use a shorter timeout, but I don't
know what it is - I'll look into it.

(Beyond that - I mentioned this briefly to Sascha - there's no hard and
fast need that I can see for the "terminal" that is being emulated by
the system console to resemble a VT100 - i.e. it could use some
character like NUL to signal the start of an escape sequence, and the
termcap entry for syscons could be adjusted accordingly.  But that's
definately experimental future work, if it's even possible.)
