James: I think this is Claim 1.

What is claimed is:
1. A monolithic integrated circuit comprising:

-programmable clock circuit means for producing a video memory clock signal and a video dot clock signal;
-a video controller coupled to said programmable clock circuit means for receiving the video memory clock signal and the video dot clock signal and for producing a video information data stream;
-random-access memory means, coupled to said video controller, for receiving the video information data stream and producing a video display information data stream; and
-digital-to-analog converter means, coupled to both said random-access memory and to said video controller, for selectively receiving either the video information data stream or the video display information data stream as received data and for converting the received data to analog video signals.


That's from patents.ibm.com and appears to be the same as the "Claim 1" I referred to (at least it matches my vague memory.)

Applicant(s): Cirrus Logic, Inc., Fremont, CA
Publication Date: Dec. 3, 1996
Application Date: Nov. 5, 1993

S3 bought a batch of patents from Cirrus Logic for $40 million (innaccurately referred to at one point in the lawsuit paperwork as the mind boggling sum of "$40,000,000 million", unless that's legal-speak or something.)
