To get InnoDB enabled in the first place, I followed instructions here: http://www.geedew.com/2008/05/21/how-to-fix-innodb-has-been-disabled-for-this-mysql-server/ Now I noticed that if I change innodb_log_file_size value and restart InnoDB, InnoDB engine and tables become unusable. After googling a bit, I found some obscure comments; Seriously? Something this important should be written to all mysql conf files if MySQL can't handle something like this automatically. This is just a recipe for panic attacks and data loss.
