I think it's not good idea to use nginx map $http_accept_language because it does not honor quality value (q in Accept-Language header). Let's imagine you have:

map $http_accept_language $lang {
    default en;
    ~en en;
    ~da da;
}

And client will send Accept-Language: da, en-gb;q=0.8, en;q=0.7

Using nginx map will always map $lang to en because it simply find in header string. But correct mapping will be $lang = da (because Danisch has quality value q=1 which is bigger then English q=0.7 in this case) More on this in RFC: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
