Rails ActiveMerchant Patch For BeanStream

I submitted the patch to active merchant plugin for Canada payment gateway BeanStream. I guess that it will take some time to get reviewed, tested and accepted ( or not accepted because the remote test can not be passed without beanstream's test account which it doesn't provide it to me), so I uploaded the patch to a google code project:
