I found in the PCI/PCI Express Configuration Space Access documentation [1] 
following sentence: PCI Express defines an Enhanced Configuration Access
mechanism (ECAM).
This means, i440FX chipset type based hardware [2] are old Pentium hardware
and PCIe did not exist on it.

I don't want to be petty but I need a "criteria" to "sort" my hardware for 
genode :-)
At least where I can use the "acpi_drv".

Again thanks for your answer and also for the support.
