I don't think we can fully drop support for these systems.
Did they have an unique PCI ID or something else that could be tested for?
Perhaps it could be just a white list like dmi_year > 1995 to disable.
Depending on how often floppies are still used this might save non trivial amounts of power on newer systems :)
Anyways it would be probably good to convert this to the new infrastructure, and remove the old hooks, but the interrupt-context issue would need to be fixed first.
