Here is some lspci lines for three different machines that exhibit this bug. The desktop machine with the ATI radeon card is pretty old but it runs World of Warcraft etc smoothly and it's not an integrated chipset like the two first machines).

Desktop with integrated intel graphics (bought this summer with a Gigabyte GA-EG45M-DS2H motherboard)
(it's an Intel G45 chipset with a X4500HD graphics card)
