Log Message:
Enable eager fpu automatically at boot time if the cpu is affected. Intel
hasn't published a list of its affected products, but it appears that Xen
was given this information since they have a specific detection code.
We could just unconditionally enable eager; but on x86_32 eager may have
a greater performance cost than lazy, and we don't want to lose
performance on unaffected (and ~old) CPUs running NetBSD/i386.
So use the same code as Xen: take Family 6, and whitelist certain models.
