I tried to respond to your NVidia forums post; but couldn't join the 
forum (apparently they didn't like my gmail address).

- FWIW I get that wait (WAIT (E, 0, 0x0887d, 0) ) when I activate the 
following kernel options:

#  set "Bus options (PCI etc.)" -> "Support for DMA Remapping Devices" 
to "*"
# set "Bus options (PCI etc.)" -> "Enable DMA Remapping Devices" to "*"
# set "Bus options (PCI etc.)" -> "PCI Stub driver" to "*"

Activating these options is prescribed by the KVM folks to allow VM 
access of the GPM; < 
http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM>

- When I deactivate those options, the NV driver works fine. kernel: 
linux-2.6.32-gentoo-r6 (and r3)

- Perhaps you could post these comments in the NV form. Perhaps you 
could also advise them that they might get more participation if they 
were a little more accessible.
