As meeroh told you on csmp, this issue has been discussed at length
several times. You can search the list archives.
One solution is to send the prefs down to your driver from user level.
But you say this won't work in your case? Why?
Anyway, I think there is another solution, that allows a driver to send
something up, maybe even showing a UI. It was discussed, but I forget
what its called, let alone the details.
