Well, some Celerons are. My laptop has a Celeron with a Coppermine core, so it is PIII based. Here is the output from /proc/cpuinfo:
processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 8 model name : Celeron (Coppermine) stepping : 1 cpu MHz : 501.140 cache size : 128 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse bogomips : 999.42
The laptop runs perfectly well when I select a PIII CPU in the kernel config. Here is a small patch that fixes the documentation:
