Default Re: IGP 8300 freezes with 177 and 180 on ubuntu

Here I could provoke stability problems with the very latest driver (185.18.08) and my trusted old 6200 card; when the BIOS was set to PnP: 'No'; because the IRQ was shared. Then I set the BIOS to PnP: 'Yes', and I got a standalone interrupt:

...
15: 0 0 IO-APIC-edge pata_amd
16: 22 8399 IO-APIC-fasteoi nvidia
19: 0 3 IO-APIC-fasteoi ohci1394
20: 25 4143 IO-APIC-fasteoi ohci_hcd:usb3
21: 9 2446 IO-APIC-fasteoi ehci_hcd:usb2, HDA Intel
...

and no more stability problems at all. Then I rebooted, removed the 6200. Alas, whatever I do now in the BIOS, I get shared interrupt for nvidia, and stability problems at once:

...
15: 0 0 IO-APIC-edge pata_amd
19: 0 2 IO-APIC-fasteoi ohci1394
20: 2 393 IO-APIC-fasteoi ohci_hcd:usb3, nvidia
21: 2 2468 IO-APIC-fasteoi ehci_hcd:usb2, HDA Intel
22: 9 1295 IO-APIC-fasteoi ehci_hcd:usb1
...

Aside of the nvidia, the interrupts remain the same. And IRQ 20 happens to be the mouse, and nvidia doesn't seem to like that at all.
So the question remains, how to get nvidia to use a free interrupt (like 16 in the earlier case)?
