Your best bet is probably to see if there's a bios update available
for your board which knows about celerons..
If that's not the case, the place for this sort of code would be
sys/arch/i386/i386/machdep.c; there are several functions in there for
CPU initialization (e.g., cyrix6x86_cpu_setup, winchip_cpu_setup,
amd_family5_setup).
