And I guess no software intervention is desired nor is planned then.

I was thinking; a small program works in background listening to an interrupt on PCI bus; and when it happens, the software disables the selected peripherals. As far as I know, there are 256 interrupt options. I might be wrong.

Wouldn't this be an easier way?

I am no PC guru BTW.
