Missing CPU ID in x86/fat/fat.c

[Achim Gratz]

Several new CPU, while already defined in the fake_cpuid_table, have no
corresponding case statement in the selection function, which seemingly
causes them to be treated as a generic P6 CPU for Intel and I'm not sure
what a Jaguar would be detected as.  The following patch copies the
corresponding lines from the x86_64 branch to (hopefully) the right
place.
