Sorry for a dumb question from the audience but how does this work 
for PCI devices? We don't worry about what drivers may be needed
because there's no "fallback / generic" driver?
For MDIO are the ID registers too complicated to expose to user space
and let it match the drivers using modinfo (avoiding the need to boot
a kitchen sink kernel)?
