Heh.  Sorry for not reading your first posting thoroughly enough.

>From the zshcontrib(1) manual:

     up-line-or-beginning-search, down-line-or-beginning-search
          These  widgets are  similar  to  the builtin  functions
          up-line-or-search  and  down-line-or-search:  if  in  a
          multiline  buffer  they  move  up or  down  within  the
          buffer,  otherwise  they  search  for  a  history  line
          matching the start of the  current line.  In this case,
          however,  they  search for  a  line  which matches  the
          current line up to the  current cursor position, in the
          manner    of   history-beginning-search-backward    and
          -forward, rather than the first word on the line.

So, you'd probably need something along the lines of this:

  autoload -Uz up-line-or-beginning-search
  autoload -Uz down-line-or-beginning-search
  bindkey '\eOA' up-line-or-beginning-search
  bindkey '\e[A' up-line-or-beginning-search
  bindkey '\eOB' down-line-or-beginning-search
  bindkey '\e[B' down-line-or-beginning-search
