It's because you are using the -U deny.  You are telling the kernel to
deny unknown permissions and then you are trying to define an unknown
permission.  There is nothing wrong with the kernel.

I do need to submit the policy path to define it, but that's not a good
idea until we know more or all of the places it is needed.  I hoped to
work on that with dwalsh in rawhide before we push the policy patch
upstream.  You can help there!  In your base policy module you need to
define 'request_module' in the system class in
policy/flash/access_vectors rebuild and load the base policy policy
module.  Then you can use the request_module permission.
