I've just set up another database to phpMyAdmin demo server - Drizzle. At first attempt phpMyAdmin did not work at all, but after few fixes (basically disabling all charsets/collation handling we do on connect), we're at least able to connect and show the interface with some databases and tables.
However there is much more things to fix (for example phpMyAdmin does not see all tables for some reason) and definitely more to test. However the question is if we want to officially support Drizzle and put some effort into it.
You can try phpMyAdmin with Drizzle here: http://demo.phpmyadmin.net/master-config/?server=3
