Could we please have this (or a proper fix) in before 2.6.20 to resolve

Subject: [PATCH] Fix some ARM builds due to HID brokenness

The new location for HID is extremely annoying:

1. the help text implies that you need to enable it for any
keyboard or mouse attached to the system. This is not
correct.

2. it defaults to 'y'. When you have input deselected, this
causes the kernel to fail to link:

hid-input.c:(.text+0x55054): undefined reference to `input_ff_event'

Fix the second problem by making it depend on INPUT. The first
problem is left as an exercise for the HID maintainers to solve.
