It appears you failed to define post_word_load(), post_word_store(), post_hotkeys_pressed(), post_bootmode_get() and post_bootmode_init() in your board specific code.
Did you read doc/README.POST ?

These appear to be unrelated to me.
By the way: you are aware that v2009.11 is totally outdated? It makes not much sense to invest efforts in extending such old code. Please do yourself (and us) a favour and update first to recent code.
