Attached you'll find a patch to user.module's user.js. It enhances the Drupal.evaluatePasswordStrength function by allowing it to check for repeating classes of characters.

http://www-128.ibm.com/developerworks/lotus/library/ls-password_quality/

This link suggests against repeating characters. I can't quite think of an efficient way of doing this in JavaScript, but we can check for classes (e.g. "abc", "123", "asdf") and increment the weaknesses variable accordingly.

A similar patch has been submitted for the 7.x branch at http://drupal.org/node/340043

At this point, no new features will be added to D6 (or D7). If you think Drupal 8 needs this feature, please assign this issue to D8.
