match routines return the "quality" of their match. So another way to
describe this is to have an interface to get the driver to change
(raise) the value it returns for match.
The real problem with doing this is that we don't have a way to identify
drivers to userland. Devices yes, but not the drivers themselves. To
really do what you want, we'd need one.
