I'm not sure Cyrix died so much as they were absorbed by IBM and worked on their future products like the Cell.
No it died. It died hard. Their staff quit just as VIA went to buy them, ended up basically buying what was left with no employees for patents (and a very important cross license agreement with Intel). Since that didn't work out VIA quickly made a second move and bought up Centaur.
Edit:
Doh. Think before you type. Sorry for the Necro. But since I brought this back up from the dead. Glad nothing ever came of it.
