Oh, good point. I forgot about that one.
Patch is to open ./includes/functions_install.php and to remove the following code snippet:
'sqlite' => array(
'LABEL' => 'SQLite',
'SCHEMA' => 'sqlite',
'MODULE' => 'sqlite',
'DELIM' => ';',
'COMMENTS' => 'remove_remarks',
'DRIVER' => 'sqlite',
'AVAILABLE' => true,
'2.0.x' => false,
),
