How long should it reasonably take to get my 06 speed 6 fixed?

Here is the history:
November 2 - check engine light goes on
November 3 - dealer takes the car in and identified the car as needing a new "swirl solenoid".
November 6 - part arrives and installed. ESU flash also performed
November 15 - check engine light comes back on.
November 20 - dealer makes an adjustment to the part just installed.
November 21 - check engine light comes back on. Dealer unable to fix the car. Order a new "development" part from Mazda. Part will not be in until December 22.
November 28 - car is returned to me. I am told it is ok to drive it with the check engine light on.

So far the check engine light has been on continuously since November 15. Is it reasonable to have to wait until the end of December (six weeks!) to get the car fixed? And even then there is no guarantee the new part will fix the car?

Welcome to the forum.
I suggest you take it to another dealer and explain all of the above and see what they can do.

I suggest you call Mazda and tell them you'd like a new car.

Welcome!

That's alittle too far.....If it's minor Mazda can fix it, Just take it to another dealer.
If they can't..then request another car, but the Speed6 is slim pickings...getting the exact same car that was acustomed to your wants probably won't be had easily.
