Arnd,

I did a bit more investigation. My original .config had CONFIG_PCI_HOTPLUG not 
defined, but did have CONFIG_CARDBUS and the various yenta modules turned on. 
With your changes, the CONFIG_PCI_HOTPLUG overrode CARDBUS.

I thought mine was a corner case, but now I am not sure. As stated above, the 
Debian 12 factory configuration for ppc32 does not turn on PCI hotplug, but the 
x86_64 configuration for openSUSE Tumbleweed does. The x86_64 configuration in 
Fedora 37 does not contain CONFIG_PCI_HOTPLUG, but does have CARDBUS set.

It seems that several distros may get the wrong result with this change,
