I also had another issue when patching the kernel.
I already had a recent kernel for the Bbone (3.8.4-bone9), which I got
following this procedure (which includes very helpful scripts):
http://www.eewiki.net/display/linuxonarm/BeagleBone?focusedCommentId=13140246#BeagleBone-LinuxKernel
Since the kernel is recent, I went on to apply the few remaining patches,
as described by Alan here:
http://permalink.gmane.org/gmane.linux.network.zigbee.devel/1493
I applied patches 0001-0005 (from patches-joao.tar.gz) but forgot to apply
the bone-dt-cape-override.diff patch. When applying patch 0001, I got the
following reject:
--- firmware/Makefile
+++ firmware/Makefile

fw-shipped-$(CONFIG_CAPE_BEAGLEBONE_GEIGER) += \
The other patches for the driver (0002 to 0005) were applied with no errors.
Pretending to ignore that Makefile patch error, I recompiled the kernel and
all seemed to work out OK.
Then it hit my that I had forgotten about the bone-dt-cape-override.diff
patch!
Trying to apply that, I got the following reject:
--- arch/arm/boot/dts/am335x-bone-common.dtsi

...which I'm afraid cannot be ignored, since when I try to rebuild the
kernel, I now get the following:

Any ideas? :)
