Ok, it's the same behavior that mano had, but since the warning didn't go
away with the trial patch, it's not exactly the same situation.

Can you send

- output of /proc/ioports both with the current kernel (or the 2.6.30
kernel - they should be identical) and with one of the kernels in
between that didn't warn

- send the full bootup dmesg with CONFIG_PCI_DEBUG enabled

and we can probably figure it out.

That said, since it's not a regression, I'm not going to _do_ anything
about it until after 2.6.31, but I might have a test-patch for you to try
ot something.
