Modern userspace and kernel facilities like media change polling do
not support all the old and deprecated IDE drivers. The IDE drivers
are just not capable to do what you are looking for. Udev does not
support IDE drivers at all, only libata.
You might just want to disable the IDE drivers in the kernel config
and use the libata ones. Ideally the kernel would just delete the IDE
stuff.
