Either this patch, or a different fix (see below), should to be sent to Linus. Otherwise, it causes a regression (lack of removable bay support in ibm-acpi). Unfortunately, I didn't notice the problem before because I had ACPI_BAY applied to my 2.6.18 and 2.6.19 test trees. The patch uses "depends on ! FOO", which means the legacy support in ibm-acpi can be selected if ACPI_DOCK or ACPI_BAY is set to "m" (module). Loading ACPI_DOCK or ACPI_BAY module along with ibm-acpi and ACPI_IBM_DOCK or ACPI_IBM_BAY could cause weird behaviour (untested) on some systems. There are alternate ways to fix this. The easiest would be to revert commit 2df910b4c3edcce9a0c12394db6f5f4a6e69c712 from Linus' tree, and I'd submit it again when ACPI_BAY is ready to be sent to mainline. -- "One disk to rule them all, One disk to find them.
