The PATA side requires the right buffers are present, and also in some situations that IORDY is not in use before the unplug.
I'm not sure what you mean but the successful ThinkPad UltraBay hotplugging which I reported earlier is with PATA DVD and PATA HDD, on ICH6M with ata_piix. I tried it many times, with no problems or unexpected dmesg entries. As mentioned, it takes an extra ACPI command to electrically turn off the port.
