Hi Heiner,
I was able to resurrect my Sony Vaio GR214EP laptop to test this patch
on an Intel 82801CAM (ICH3-M) chipset. And as I suspected, it does not
work. I get the following error in the kernel log:
[13563.411101] i801_smbus 0000:00:1f.3: SMBus using PCI interrupt

[13565.439189] i801_smbus 0000:00:1f.3: Failed terminating the transaction
If it matters, and as seen in the list of handlers above, IRQ9 is
heavily shared on this laptop (ACPI, USB, graphics, PCMCIA, sound,
network and SMBus).
