At the end I've added a couple of small patches to the kernel to report the
PCI bus type as it sees it. As it the problem is with the PROM related code,
as prom_getproperty calls return an empty string regardless which property
is queried.
The PCI controller has the following type:
compatible pci108e,a801
pci108e,8001
thus, looking at the kernel source, it should be driven as a SCHIZO PCI
controller. (the id pci108e,8001 is included there). After hardwiring this
type to the detection code the driver initialization tries to look up the
'reg' property, but this again fails:
POSIX conformance testing by UNIFIX
PCI: Probing for controllers.
SCHIZO: Fatal error, no reg property.
So as it seems it is a PROM handling related problem.
