Manuel, could you compile your kernel with CONFIG_PCI_DEBUG enabled, and then boot it with "pci=earlydump", and send me the dmesg of a kernel boot? You may need to make sure that CONFIG_LOG_BUF_SHIFT is big enough to get it all, and perhaps use "dmesg -s 1000000" (some versions of dmesg will truncate the result to 64kB or something by default, and depending on just how verbose your boot ends up being, you migth lose things).
