WebSphere Portal 6 certainly supports JSR168.
If you're doing WebSphere portal development, you likely have access to Rational Appilcation Developer. That tool provides a portlet development toolset that allows you to create, compile and deploy JSR168 portlets. It also provides extra features such as C2A and Portlet Services.
Having said that, WPS can handle a standard JSR168 portlet developed in any environment.
