When updating this IBM ThinkPad T43p from 2.6.22 to 2.6.23-rc1 using make oldconfig, the text and default Y of config THINKPAD_ACPI_INPUT_ENABLED bool "Enable input layer support by default" depends on THINKPAD_ACPI default y ---help--- Enables hot key handling over the input layer by default. If unset, the driver does not enable any hot key handling by default, and also starts up with a mostly empty keymap. If you are not sure, say Y here. Say N to retain the deprecated behavior of ibm-acpi, and thinkpad-acpi for kernels up to 2.6.21. made it sound like a good thing, so I configured it Y. But its only effect seems to be to disable the key I use most, Fn+F4 to suspend to RAM. It also disables Fn+F3 to blank the screen, though I don't use that one; but does not disable the brightness and ThinkLight keys, presumably because they just get mapped to KEY_RESERVED. The same remains true with latest kernel git. Perhaps there's some other config option without which this option is useless, which I don't have set? My .config for latest git attached. I get along fine now with THINKPAD_ACPI_INPUT_ENABLED disabled; but suggest that its text is misleading, and default Y questionable. Or perhaps there's a bug, and I can help try patches. Thanks, Hugh
