It is possible with default Magento. You need to create attribute for manufacturer and then filter out your products.
However, default Magento functionality is laking of custom filtering system.
In case you are interested with the solution with more flexible filters, I can offer you Store Manager for Magento application.
Using it you will be able to filter, add, modify the products depending on suppliers by means of filters, expressions and sqls.
Free 14-days version of the application is available for download from the link in my signature.
If any assistance is required, let me know and I will guide you through.
