Aha! This setting can be found in the GConf editor (registry):
Apps->gnome-terminal->keybindings
Setting to 'disabled' turned it off. This disabled F1 for all
'gnome-terminal's that I opened after changing the setting. The setting
is applied -on-the-fly- and is immediately reflected in (all) open
gnome-terminals.
You can script (php->exec/system) this, take a look:

That should do what you want... as for the actual grabbing of the
keys, I don't have (php)ncurses set up on this machine (or one that's
handy at the moment) to try.
