Add models for 486SX, and pre-CPUID versions of the 486 (DX SX).
Change the model number for the standard 486DX to a model which
actually had CPUID.
Note: these models are fairly

I think it fell through the cracks due to the RFC tag. Patches 1 and 2
look good, but Anthony does not apply TCG patches. CCing Blue and Aurelien.

I personally wouldn't object to 486 changes, but I guess it should
rather be handled via Igor's CPU static properties that I have in my

Now, all this said... if the only objection is the change of model
number for 486 then I suggest just dropping that.
