Re: Trying to make headway into finding the Xid crashes source...
You'll probably need to fiddle around a bit. On my system, noacpi... isn't really. The interrupts seem a bit random, in fact the settings in the BIOS only seem to partially correlate with the what cat /proc/interrupts reports. Make however sure you have the latest beta version of your BIOS.
After all, just as an experiment, you can try disabling USB in the bios and use PS/2 connectors for the mouse and see if that helps.
