This looks like a question-generator to me. Well, the "no driver assigned" means just this. There is no way to know, whether this is a problem or not. There are PCI devices which are (currently) treated as if they were on the ISA bus (and those will be logged with that message, if no special precautions are taken). Then there are CPU and PCI support chips, which have to be initialized for POST to complete, and there is no use having drivers for them. I'll probably make the "no driver assigned" message go away for all kinds of support chips (CPU to PCI bridge, standard ISA peripherals, ...), since those can be identified by their PCI class code. (This is already done for PCI graphics cards.) If there are PCI devices being operated in ISA compatibility mode, then there should be a dummy probe in "ign_probe()" in file "/sys/pci/pcisupport.c". This will make the misleading message go away ...
