And from the horse's mouth:

"Articia S is the first ready-to-market chipset of the Articia family of chipsets. It is a highly integrated, low-cost and high-performance system IC, ideal for network computers, web servers and thin servers. [...] Articia S is the leading system controller that enables AGP support for RISC processor based systems. It meets the increasing demands for today's embedded systems, such as video/3D graphics oriented, multi-tasking and real-time applications."

No doubt that the ArticiaS wasn't ready for any commercial product, but that doesn't mean that MAI didn't try to make and sell it for exactly that or that MAI didn't claim it to be designed for end-user markets.
Regarding PA6T and end-user markets, you should keep in mind that it was originally designed as a chip for Apple laptops.
