[Plugin: WP-Paginate] pagination

It looks like you want to at least edit the custom\pagination-posts.php file:

Change:

<?php
	}
	else {
?>
	<div class="page-nav fix">
		<span class="previous-entries"><?php next_posts_link('<span class="icon">&nbsp;</span>'.__('Older Entries', 'suffusion')); ?></span>
		<span class="next-entries"><?php previous_posts_link('<span class="icon">&nbsp;</span>'.__('Newer Entries', 'suffusion')); ?></span>
	</div><!-- page nav -->
<?php
	}
}
?>

To:

<?php
	}
	else if (function_exists("wp_paginate")) {
		wp_paginate('before=<div class="page-nav fix">');
	}
	else {
?>
	<div class="page-nav fix">
		<span class="previous-entries"><?php next_posts_link('<span class="icon">&nbsp;</span>'.__('Older Entries', 'suffusion')); ?></span>
		<span class="next-entries"><?php previous_posts_link('<span class="icon">&nbsp;</span>'.__('Newer Entries', 'suffusion')); ?></span>
	</div><!-- page nav -->
<?php
	}
}
?>
