 Who:   Venkatesh Pallipadi <[EMAIL PROTECTED]>
+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+Why:   /proc/acpi/button has been replaced by events to the input layer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.
