Thus the older Celerons should be compiled with CONFIG_M686 (Pentium
Pro),
but the Celeron Coppermine can be compiled with CONFIG_M686FXSR (Pentium

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:
