Also seems fixed in current emacs-23 branch.

When whitespace-mode is enabled and the buffer is scrolled such that
only part of a long line is visible at the top of the buffer, it becomes
impossible to scroll the window down using the down arrow.

This can be reproduced from ‘emacs -Q’ with
  C-u 99 <return>
  M-<
  C-u 99 a
  C-u 0 C-l
  M-x whitespace-mode
followed by pushing <down> until the window scrolls (it won’t!).
