It is strange that the stepping is unknown too but the logic seems fine
from reading the code except semantics where p should be equal to
Celeron (Covington). I guess you can start hacking at it inserting print
statements...

[snip bunch of lookaround paragraphs]

It is c->x86_mask that is getting clobbered somewhere. This accounts for
the stepping being unknown and the capabilities line having numbers in it.
The question is where is it getting clobbered at? I am tired and hot and
am not sure where it is getting set but I'll look at it later if someone
hasn't already figured it out by then.
