Okay so I've found another issue. For some reason, when the system is 
hibernated (e.g. lid is closed), the module seems to unload itself and the 
whole netvm freezes, requiring a "kill vm" and restart for it to work again. 
Any ideas on the cause of this?

It's impossible. It's a known bug with Xen and nVidia drivers past version 
3.19.xxx or something like that. See this thread: 
https://devtalk.nvidia.com/default/topic/691565/geforce-driver-problem-on-centos-6-4-with-xen-installed/

The only way is to use Nouveau. Problem with that is, Nouveau doesn't support 
new-ish GPUs without upgrading to kernels past the current Qubes supported 
kernels. So, nvidia owners are SOL with Qubes atm.
