+What:	i2c_adapter.dev

+When:	July 2007
+Why:	Superfluous, given i2c_adapter.class_dev:
+	  * The "dev" was a stand-in for the physical device node that legacy
+	    drivers would not have; but now it's almost always present.  Any
+	    remaining legacy drivers must upgrade (they now trigger warnings).
+	  * The "list" duplicates class device children.
+	The delay in removing this is so upgraded lm_sensors and libsensors
+	can get deployed.  (Removal causes minor changes in the sysfs layout,
+	notably the location of the adapter type name and parenting the i2c
+	client hardware directly from their controller.)

+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.

+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
