Since you don't know how that is used in the driver, that could
very well keep the security hole open as long as the driver is loaded.

You still have the obvious options that you won't like:

1. stay on an older (broken) kernel
2. don't use fglrx until this is fixed
3. copy the new compat_alloc_user_space as an inline function
into the wrapper module (possibly making it undistributable)
