You could just replace this line in the plugin:

PHP Code:

$vbulletin->templatecache['SHOWTHREAD'] = str_replace($find,$breadcrumbs.$find, $vbulletin->templatecache['SHOWTHREAD']); 


with this:

PHP Code:

vB_Template::preRegister('SHOWTHREAD', array('breadcrumbs' => $breadcrumbs)); 


And then just manual put {vb:raw breadcrumbs} into the SHOWTHREAD template.
