Geeklog works with MySQL 3.22.32!

If anyone's interested, yes it IS possible to run the latest geeklog 1.3.5 on an ancient version of MySQL ;-) Really all that has to be done is modify the 'group_assignments' table changing the ug_grp_id column definition as follows

ug_grp_id mediumint(8) NOT NULL default '0'

and get rid of the corresponding nulls inserted by default, change them for zeroes.
