yes it is supported, but the installer script will have to be modified to specify 'ENGINE=MyISAM', instead of 'TYPE=MyISAM', if you _must_ run it under 5.5.8.
what i do, is simply run any local install script on WAMP with mysql 5.1 enabled, then switch over to 5.5 and poof workie

wamp allows you to have multiple flavors of apache, mysql, php at the same time and to switch between them with mouse clickies
