How is this relevant to a chipset driver adding support for future products?
Well I have to agree with thisisaname where they state, though they are unclear to incorrect on how the iGPU works, a detail I will cover in a sec:
An APU contains a iGPU, which I'm assuming I driver for would be included in the chipset driver or am I wrong?
Yes I am taking a cheap dig at AMD but they do create some nice graphics cards then go and shoot themselves in the foot with poor release drivers.
Look at the article how the 6800 is quicker than the 7800 running under Linux.

Edit: I want them to do much better, I want all the performance when I buy the thing not a couple of year later!!
You do need a separate graphics driver for the iGPU BUT iGPU is housed on the IOD for 79/78/7600 series and directly on the die of the newer chips mentioned in the article. So I would be surprised if there wasn't something in the chipset driver to help facilitate certain shared functions/resources like ram access to/from the iGPU to shared system memory. So as a whole I don't think your wrong.
I had a few issues, for example, one of which my iGPU is not working properly with a dedicated card in on a 7950X. But as expected my 4090 covers those short comings for the most part. I'd prefer running my secondary monitor on the iGPU for example but I can't as the screen colors/pixelation and even something remincint of 'scanlines' cause the image to look nearly incomprehensible, unless I take my 4090 out and run it vanilla...
Amd GPU drivers in particular but also their software stack as a whole has been weaker than companies like Nvidia and Intel but they do seem to be slowly bringing things up to speed. Its an issue AMD has always had IMO (started with a AMD K2 in my GF's computer in the 90s and grew from there, for me) and I think it has a lot to do with market share and resources. This is why I am happy to see Ryzen/Epyc make such good headway in the market. This allows AMD to increase their war chest for things excatly like software support, R&D, and talent recruitment, helping them catch larger players with what is essentially a smaller company. But their approach is not without it's pitfalls and for now just like times in the past, stabiltiy issues are plaguing AMD on more fronts than some of us would like.
Now for me the question is will they ever reach their (our?) goal in their software stack/drivers and deliver something stronger than their past entries. I could go either way. AMD's history says they'll struggle to get industry support more times than not and that they won't or can't put in the effort needed to get their software as refined as it should be but tech histroy as a whole says everything can turn on a dime with the right product. So my fingers are crossed!
