1st, I installed mod_security to my existing apache server:
http://blog.bodhizazen.net/linux/how-to-mod_security-ubuntu-904/

2nd, As root
vi /etc/apache2/conf.d/modsecurity/modsecurity_crs_05_customrules.conf

In this file, place the following:

----

<LocationMatch "/phpmyadmin/tbl_change.php">
SecRuleEngine Off
</LocationMatch>

<LocationMatch "/phpmyadmin/sql.php">
SecRuleEngine Off
</LocationMatch>

<LocationMatch "/phpmyadmin/managecontent.php">

</LocationMatch>

<LocationMatch "/phpmyadmin/import.php">

</LocationMatch>

<LocationMatch "/phpmyadmin/tbl_select.php">
SecRuleEngine Off
</LocationMatch>

<LocationMatch "/phpmyadmin/tbl_replace.php">

</LocationMatch>
