+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:

+What:   /proc/acpi/button
+When:   August 2007
+Why:    /proc/acpi/button has been replaced by events to the input layer
+        since 2.6.20.
