[3vi1 <901386@xxxxxxxxxxxxxxxxxx>]

Looks like I have to back off the "without issue" in my previous
statement.  I just noticed that the USB3.0 devices attached to my Marvel
88SE91xx adapter are not being seen when I use this workaround.  Of
course, at this point I'm assuming it's caused by the work around and
not an entirely separate bug in 3.2.0-6... so take that for what it's
worth.

I had to completely power-down/power-on and boot back to the mainline
rc4 kernel (the only 3.2 kernel that's not had this nvidia issue for me)
in order to get the USB3 devices seen again (that is to say: just warm-
rebooting and choosing the old kernel from grub didn't work - had to
completely power down the motherboard before they could again be seen).

I also tried using intel_iommu=igfx_off, but the kernel still fails to
load the nVidia drivers in manner described in the original bug when
doing that.
