Comment 37 for bug 162671

benbois,
  There was a patch in the upstream that disabled this because it was address faulting the driver. I am in the process of cleaning up the pci and memory addressing to fix 32 bit'isms etc. which are probably responsible. My intent once I get thru this bit of overhaul and get it to run on my own systems is to put together a kernel package for you and others to test. Stay tuned.
