Nokia N900 Maemo key remap

Issue: The bar symbol is missing on the N900 keyboard:
bar symbol ("|"):
File: /usr/share/X11/xkb/symbols/nokia_vndr/rx-51

In section:
xkb_symbols "nordic_base" {

Change:
key { [ c, C, bar, sterling ] };

Issue: The N900/Maemo sends Keypad_Enter, not Enter. Causing various things to fail on a remote tmux ssh session:
.tmux.conf: bind -n KPEnter send-keys Enter
