I am experiencing the same problem.
My Host (Globat) is using MySQL 4.x and I have no problems with regular Wordpress installations.
My Host requires I use phpMyAdmin 2.5.2-pl1 to interact with the database.
I am getting a database error in phpMyAdmin as follows:
//////////////////////////
Error
The additional Features for working with linked Tables have been deactivated. To find out why click here.
//////////////////////////
When I click on the 'click here' link I get the following:
/////////////////////////
Database rmotnwpmu running on localhost
PMA Database ... not OK[ Documentation ]
General relation features Disabled
////////////////////////
rmotnwpmu is my database name.
When I click on the 'Documentation' link I get the following:
////////////////////////
$cfg['Servers'][$i]['pmadb'] string
Starting with version 2.3.0 phpMyAdmin offers a lot of features to work with master / foreign - tables. To use those as well as the bookmark feature you need special tables with a predefined structure, which we explain below.
If you are the only user of this phpMyAdmin installation, you can use your current database to store those special tables; in this case, just put your current database name in $cfg['Servers'][$i]['pmadb'].
If you are setting up a multi-user phpMyAdmin installation, you will need to create a new database and setup special privileges, so, as superuser:
create a new database for phpMyAdmin:
CREATE DATABASE phpmyadmin;
Note that "controluser" must have SELECT, INSERT, UPDATE and DELETE privileges on this database. Here is a query to set up those privileges (using "phpmyadmin" as the database name, and "pma" as the controluser):
GRANT SELECT,INSERT,UPDATE,DELETE ON phpmyadmin.* to 'pma'@'localhost';
do not give any other user rights on this database.
enter the database name in $cfg['Servers'][$i]['pmadb']

I am persuing this with my hosting company, but am not sure they will help. If they do I will update this with my results.
I am posting this for those who are experiencing the same problems as described as something to check into.
If you are successful, pls share your results here.
Thx.
