PCI quirks not handled and config space differences on resume fromS3

Hi,
it seems that PCI quirks are not handled on resume which results
in all kinds of strange effects, like disappeared PCI devices.
Below is a diff between "lspci -vvvxxx" before and after resume
for my SMBus device which only gets enabled by PCI quirk handling.

Besides that, a number of drivers do not restore the pci config
space of their associated devices properly on resume from S3.
These drivers (and associated devices) are:
- intel_agp (Host bridge: Intel Corp. 82855PM Processor to I/O Controller)
- ? (PCI bridge: Intel Corp. 82855PM Processor to AGP Controller)
- uhci_hcd (USB Controller: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller)
- ? (PCI bridge: Intel Corp. 82801 PCI Bridge)
- ? (ISA bridge: Intel Corp. 82801DBM LPC Interface Controller)
- piix_ide (IDE interface: Intel Corp. 82801DBM (ICH4) Ultra ATA Storage Controller)
Diff between "lspci -vvvxxx" before and after resume for all
problematic devices on my machine is attached.
Are there any patches I can try?
Regards,
Carl-Daniel
