I think there is some confusion in the name "Celeron". AFAIK there are two kinds of Celerons: the original PII based Celeron, or the newer PIII based Celeron. My laptop has a PIII (Coppermine) based Celeron, and it boots perfectly well without your patch.
If you are using a PII based Celeron, you should compile the kernel with support for the "Pentium-Pro/Celeron/Pentium-II". You certainly should not try to run a kernel with support for P4 on a "lower" CPU, read the documentation about CONFIG_M386 in Documentation/Configure.help for more information.
