Yes, I remembered this yesterday. I started to try to understand how 
work acpi_register_gsi and if it was safe.

I was wondering if we shouln't call it only when a driver register the 
device (to do something like pci_enable), but it will need pnp layer 
modification.

I updated the patch in order to keep PIC and TIMER.

I know, but it is already in pnpbios and I believe we should only put 
device that are problematic.

Thanks,
