I have already spent some time tracking this down, it turns out that
there are multiple keyboard cursor modes. On startup vim switches to
one of those and then expects the terminal to respond accordingly.
The reason why it worked with TERM=linux is that the linux console
doesn't support those modes, vim knows this and doesn't try to switch.

I have now added some code which implements the mode switching and the
arrow key should work with current git master. Would be nice if somebody
could confirm this. There is also a hack included which makes the keypad
somewhat useable when used with putty.

I have heard that there are a few problems with certain keys
(home/end/backspace) which don't work in emacs. I have left this as an
exercise for an emacs user ;) Jokes aside, i will try to fix this too
but i am a bit busy right now. So your welcome to contribute a patch.
