I'm not sure what PCI breakage you're referring to, but a lot of the Cardbus-centric "breakage" isn't a regression - it's new machines with weird PCI BIOS setups being incompatible Linux's current PCI bus handing strategy.
I've been trying to get this fixed for a considerable time, but linux-pci folk seem to be disinterested.
The assumption that the PCI BIOS will sanely assign the PCI bus numbers and that Linux does not need to reassign them is looking increasingly incorrect - most of the Cardbus "why can't the system see my card" are resolved by passing "pci=assign-busses", which causes the PCI subsystem to renumber all PCI busses.
So far, no one who has tried this solution has reported any additional problems that I'm aware of.
Therefore, maybe that should become the default behaviour?
