Hi Christian,
thanks for the quick answer.

The reason is not the missing
PCIe capability but that Qemu's i440FX chipset does not support
ECAM/MMCONF (memory-mapped) PCI configuration space access.
I found in the PCI/PCI Express Configuration Space Access documentation [1]
the
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.
