Comment # 9 on bug 84017 from Christoph Brill

I played with the cmdline "radeon.msi" and couldn't get any of the PCI-MSI-edge
counters to show anything else than 0. No matter which value used and no matter
if any 3D operation was done.

I haven't touched "pci=nomsi". It looks like MSI is not working at all on this
chipset ...
