"nouveau.config=NvMSI=0" does seem to work around the problem. A patch to disable MSI on these chips was linked in the upstream bug report:
https://bugs.freedesktop.org/show_bug.cgi?id=87361 http://lists.freedesktop.org/archives/nouveau/2014-December/019417.html
dmesg still mentions "MMIO write FAULT" multiple times, but that's probably a separate bug; at least it hasn't frozen or scrambled yet.
If I should open a separate report, or provide any additional information, just let me know what you need.
