+What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY)
+When: 2.6.21
+Why: hotkey.c was an attempt to consolidate multiple drivers that use
+ ACPI to implement hotkeys. However, hotkeys are not documented
+ in the ACPI specification, so the drivers used undocumented
+ vendor-specific hooks and turned out to be more different than
+ the same.
+
+ Further, the keys and the features supplied by each platform
+ are different, so there will always be a need for
+ platform-specific drivers.
+
+ So the new plan is to delete hotkey.c and instead, work on the
+ platform specific drivers to try to make them look the same
+ to the user when they supply the same features.
+
+ hotkey.c has always depended on CONFIG_EXPERIMENTAL

+What: /sys/firmware/acpi/namespace
+When: 2.6.21
+Why: The ACPI namespace is effectively the symbol list for
+ the BIOS. The device names are completely arbitrary
+ and have no place being exposed to user-space.
+
+ For those interested in the BIOS ACPI namespace,
+ the BIOS can be extracted and disassembled with acpidump
+ and iasl as documented in the pmtools package here:
