Hello!
When working in cpu autoconfiguration I found some problems:
I have to identify this processor:
Vendor: Intel
Family: 6
Model: 8
Is it a "Pentium III (Coppermine)" (setup.c:1709)
or a "Celeron (Coppermine)" (setup.c:1650) ?

AFAIK, both. Coppermine is the code name of the low level arch of the chip.
Really, the kernel should be querying the builder: Have you a Deschutes, a Mendocino or a Coppermine ? How much cache do you have ? But that is rarely known (Uh? I bought a Pentium III). You have to guess from the answer to:
Have you a PII, an old Celeron (Mendocino) or a new Cel-PIII (Copper).
Thus the older Celerons should be compiled with CONFIG_M686 (Pentium Pro),
but the Celeron Coppermine can be compiled with CONFIG_M686FXSR (Pentium III), right?
In this case we should update the files Configure.help and the config.in files.

I am not an expert on arch codenames, models and so on. Perhaps you should launch a more specific question onto the list and see what happens...

Yes.

I supplied a patch which did that, but Linus dropped all patches (on purpose). Here it is again:
