Drupal 7

http://drupal.org/node/606304

disabling eaccelerator in .htaccess lets D7 work

php_flag eaccelerator.enable 0
php_flag eaccelerator.optimizer 0

otherwise, we get the error:

PHP Fatal error: Class 'FieldException' not found

Thanks to axper and Darko Hrgovic

Drupal 7 is up and working! About time!
