In case of a modular kernel it seems to be sufficient to load thinkpad_acpi or 
the bay module before libata. This can be achieved on Debian based systems by 
adding "bay" to /etc/initramfs-tools/modules and rebuilding the initramfs for 
the current kernel with "update-initramfs -k $(uname -r) -u -t"
