Thanks.  I think this should be only for specific PCI IDs.  Or more
better, create a new model to enable it.
Is the PCI SSID of your device 10f7:8338 ?

Your patch cannot be applied to the latest code because of code
changes.  The patch below adds a quick fix based on your information
(for 2.6.25 or later).  Could you give it a try?
