ACPI_BAY is still experimental, and breaks completely on ThinkPads if whatever is in the bay is not a disk (e.g. if it is a battery), at least during boot. Also, some thinkpads benefit from *optional* extra intelligence on bay handling during STR (which is not in ibm-acpi yet). E.g. a T43 can save a few watts if you power off whatever is in the bay right before STR, *as long as it is not a battery*. This is just an interim patch to let people easily disable ibm-acpi bay support. Another patch making it default to N and depend on !ACPI_BAY can be added later, but since I did not have a time window to work on ACPI_BAY + ibm-acpi interaction yet, I fear it is a little early for that. -- "One disk to rule them all, One disk to find them.
