 Again, I've only been able to test the one machine that never exhibited
 the original problem.  It still works fine.  I did notice the following
 in 'dmesg' output either starting or exiting the Xserver:
 
 [   153.346307] nouveau0: autoconfiguration error: error: user: nvif_object_map, -12
 [   153.346307] nouveau0: autoconfiguration error: error: user: channel failed to initialise, -12
 
 
 I could not test with MSI as it is disabled in the HEAD revision of
 
   sys/external/bsd/drm2/dist/drm/nouveau/nvkm/subdev/pci/nouveau_nvkm_subdev_pci_base.c
 
 I've rolled it back to the previous revision in my test tree for the
 next round of updates, but that'll take at least 24 hours to build due
 to the recent kernel bump (8.99.35).
