Then it's not exported correctly (I'm 99% sure that's the case)!

Hmm. So this is a driver that is delivered as a module, not as
source-code? In that case I'd recommend one of the following options (in
no particular order):
1. Find a different hardware vendor that has a open-source driver. 
2. Use one of the hardware vendors preferred distros. 
3. Try to find a slackware version of the driver.

Is this a PV or HVM domain? You can't export PCI devices to HVM domains.


Other than that, I can't see how one would work and the other not.
