Linus' GIT tree 2.6.26-05752-g93ded9b shows this message:
i801_smbus 0000:00:1f.3: PCI INT B -> GSI 19 (level, low) -> IRQ 19

There is no equivalent in 2.6.26 or previous kernels.

I believe this message in itself needn't be a problem but the code producing this warning isn't new...
Bjorn, this reminds me of the:
pnp-have-quirk_system_pci_resources-include-io-resources.patch
in Andrew's tree that I need to have my soundcard not fail due to the IO resource being claimed by PNPACPI. The fact that I needed it was new to 2.6.26 (but going back to 2.6.25 I all of a sudden also needed it there which made me conclude that some BIOS reconfig had occured).
ACPI isn't doing odd things I hope?
