Still testing, but the idea is to use the patch against Drupal 7.4 which supposedly already works, at least with an older version of hiphop-php. If it works, then we can try to move forward and troubleshoot the setbacks. Would be great to submit some Drupal core patches that would get vanilla drupal core working with hiphop-php...
