My next question is whether the problem is in the setting or in the
reading. You may in fact be setting the value but some problem with
lspci's interaction with the chipset is reporting zeros incorrectly.
I'm going to try and come up with some method of measuring the actual
performance, then see if it changes when I change the values on my
Tehama board, which reports zeros as your nforce2 does. That
machine's idle at the moment so I can dink around with it.
So far everyone seems to have assumed that the "setting" is the
problem, which may in fact be true, but we don't have any proof of
that yet. setpci doesn't report an error, so either setpci or lspci
is behaving badly.
