I think you are right that SinfulWeeper has some facts crossed. IBM fabs made the later Cyrix chips (6x86/MII) until National bought Cyrix and paid a fabulous fortune to get out of the contract. Cyrix never had any fabs until the one National Semiconductor built for the purpose. IBM also made the Cyrix chip with the IBM brand on it. I'm sure this was a condition of the contract with IBM.
Earlier Cyrix chips that I remember were made by Texas Instruments. (My recollection of the original Cyrix is that it was an independent design company formed from capital supplied by several semiconductor manufacturers with the intention of legally cloning Intel's designs, so as to get a piece of Intel's action. It was a separate corporation to insulate the chip manufactures from liabilty in case the legalistics did not work out. By the time of the 6x86 the supporting companies had given up, and Cyrix was simply an independent design corporation.)

I don't recall that, although I don't see why AMD might not have contracted IBM to do it. I think AMD had its own fabs to produce 286s, 386s, and 486s. AMD and Intel had mutual cross-licenses to produce and sell each others designs going back to the time when chip buyers would not buy chips that had only a single source. Intel screwed AMD by not producing AMD chips as an alternate source, leaving AMD hanging. Up to and including 486s, AMD produced improved versions (usually faster and much cheaper) of Intel chips using Intel's die design obtained through Intel. Intel wanted to break the contract and took AMD to court with the 486. There were huge legal battles of course. AMDs sales soared as people rushed to obtain the superior and cheaper chips before they might be taken off the market by the courts. During periods when the court rulings were unfavorable to AMD, they said some 486s produced were AMD's own design.
AMD produced some 586s of its own design and some much better ones from the NexGen purchase.

Could be. But the more you say about things I recall differently, the less believable what you say sounds.

I know AMD is working with a lot of companies. Most chip-making subsystems are contracted and bought from other companies. This goes for every chip maker really, and this sort of thing is the general case with all corporations. Ford does not make the seats it puts in its cars. Intel does not make the 300mm wafers it uses in its fabs. The HD heads used in the major manufacturers drives are bought from IBM. But I really don't think IBM is tied to AMD any closer (or less) than Intel. I'm sure AMD would love to be though.
At one time IBM used to make altered versions of Intel's 486 (486SLC2) with the IBM brand. I owned a motherboard that had one (actually I still have it -somewhere). IBM didn't make CPUs with Intel's brand. IBM just had rights to make special versions for its own purpose. Younger people may find this hard to believe, but IBM was such a major force then it could get contractual favors unlike any other. As I understand it, IBM got Intel to agree as part of their contract to buy Intel chips.
I really think IBM has wanted rights to produce x86 chips ever since it gave up the contract with Cyrix. AMD probably would like to improve its finances, and getting together with IBM could help. Don't be surprised if you see IBM motherboards with chips that seem eerily like Athlons some day.
IBM - Intel - 486
IBM - Cyrix - 6x86/MII
IBM - AMD - ???
