not to worry: recent linux kernels autodetect the
cache: but if for some reason they get it wrong, you
can override using a kernel option:

"cachesize=

...Override level 2 CPU cache size detection.
Sometimes CPU hardware bugs make them report the cache
size incorrectly. The kernel will attempt work arounds
to fix known problems, but for some CPUs it is not
possible to determine what the correct size should be.
This option provides an override for these situations."

/linux/Documentation/kernel-parameters.txt, ll.291-6
(kernel 2.6.12.5)
the way up and the way down are the same (heraclitus)
