It came about because the previous setup was a mess. It's in 2.4, and
some versions of 2.2, because USB input devices are pushed through it, as it
appears ADB can be in 2.4. It provides a more consistant interface for
using input devices. It also tries to move drivers into the kernel, instead
of having every device talking it's own protocol, needing X and gpm, etc to
support it. There's more information on the main page:
http://www.suse.cz/development/input/
Hopefully the input layer will be merged in it's full glory as part of the
linuxconsole rework in progress for 2.5,. (linuxconsole.sourceforge.net)
You should be able to tell if your kernel supports the input layer by
checking if charmajor 13 is registered for input in /proc/devices, or
watching the logs for the device attachment/detection messages.
In 2.4 kernels there is an "Input core support" section which contains the
structure config options. Then you'll heed to enable the input core using
drivers for your input devics, probably CONFIG_INPUT_ADBHID aka: Use input
layer for ADB devices. I'm not positive about this part because my PMac is
powered off at home right now. I greped my x86 2.4 tree to find that.
