On trying to build a 2.6.21.1 kernel using the configuration at

You've got CONFIG_BT_HIDP=y there but CONFIG_USB_HID=m. The trivial
patch below solves it. To test, you can just "make oldconfig" on the
same .config that broke above and then proceed to make bzImage.

Make CONFIG_BT_HIDP depend on CONFIG_USB_HID and CONFIG_HID_FF.
