SLES10 with SLES10 SDK add on timeout

I have integrated the SLES10 SDK as an add-on product with a SLES10 install source. However, when I run an autoyast install, I get prompted for the SDK license agreement. The SLES10 license agreement times out. How do I get the SDK and other add-on product license agreements to be timed out so the install will complete without human intervention? -jason
