Here's another idea, you can ship late. There has to be a really good reason to meet the Monday deadline and it must be really important to the company. In fact it would be so important that the people and departments would know that it's important. They wouldn't find out about it on the weekend the day before it ships. Sounds like these people designed a component that wouldn't work on the current infrastructure. That happens, but if there is a big oversight like this, then you should ship late, instead of risk taking everything down.
