With a table that has a 'bit' datatype, I get an error that 'bit' datatype is an unknown database attribute type.

This is in 1.0 beta 2.

BIT is a valid mysql datatype as fo 5.0.3, according to  http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html

Table creation SQL:

CREATE TABLE  `corpworlds`.`log_logins` (
  `id` int(11) NOT NULL auto_increment,
  `datetime` timestamp NOT NULL default CURRENT_TIMESTAMP,
  `login` varchar(40) default NULL,

  `ip_address` varchar(25) NOT NULL,
  `browser` varchar(100) default NULL,

  CONSTRAINT `fk_user_id_logins` FOREIGN KEY (`user_id`) REFERENCES `acl_users` (`id`)
