I have this vague recollection that the metaesc keymap flag used to make alt-left and alt-right work in the console, however, it doesn't seem to work now and I can't see from the CVS history any point where it ever worked, so maybe I am mistaken. In any case, the diff at the end of this mail makes it work, although I am not sure it is right to allow all of KS_GROUP_Function. This is most useful for irssi, but there may be other programs too.
