Neither, actually. From your link (and it agrees with my memory from last night):
pci=noacpi Don't use ACPI to set up PCI interrupt routing.
pci=routeirq forces the all the routing to be done up front (the old way), rather than waiting for each device's driver to request configuration for the device and route it then (the new way)
As I took it from my searching, pci=routeirq is a smaller hammer.
Actually, one of the things I want to get working is thermal monitoring, and making sure that ACPI is managing the fan speed correctly and using the CPU scaling to reduce power when it's mostly idle. It's going to double as a server (I think it can run cooler than my old desktop)...given that it's always on, I'd like to minimize power consumption and noise output.
Thanks. On my last couple of computers it's definitely been the video configuration which has been the nightmare. I had to jump through some hoops on that here, too, actually. I still need to go back and tweak it to my satisfaction, and then you'll probably see an xorg.conf here.
