On the other hand, I would be thoroughly surprised if Linux didn't use or
find your L2 cache, since this is something enabled or disabled at the
hardware level, not from within the kernel, and I have certainly never
heard of any cache problems with Linux. So in the end, it /may/ be a
shortcoming of the /lshw/ version on your live CD, or possibly a flaw in
the kernel's ring buffer output.

I did as you said part of my dmesg output is:

[ 31.644605] CPU: L1 I cache: 32K, L1 D cache: 32K
[ 31.644606] CPU: L2 cache: 6144K

[ 31.665349] groups: 03

Now does this mean that the kernel uses the l2 cache, or that this is
part of the message
that the e8400 spews? I see no message in the entire dmesg output
that the l2 output
has been disabled or anything out of what I would expect...
