Hi!
So some 486 processors do have CR4 register. Allow them to present it in
register dumps by using the old fault technique rather than testing processor
family.
I thought Andi commented this as "way too risky", for little

I think the 486's that have CR4 are the same that have CPUID, and thus
can be tested for by the presence of the ID flag.
