Nope, it's not really a kernel issue, there are cache checkers around
(mail me if you want a copy of one sent, be aware it's a dos program), but
not in the kernel. The only thing about these chips that's illegal is
passing them off as real, there is a case for filling the spaces in the
motherboard (the sockets) with blanks (ie a chunk plastic with legs, and
nothing else), but there are blanks with things like "write back cache"
printed on, which are misleading and illegal. The basic thing is that
as long as the blanks arn't passed off as real, there's no problem, ie as
long as you havent been lead to bleave that it has a cache ....
