Hi Koen--
Thanks for the explanations. One more question:

When I'm in the process of making a kernel change, re-compiling, watching it
fail, make another change, etc. it can be a bit of a hassle to bump up either
MACHINE_KERNEL_PR or the _PR_append value. Instead, I've tried just touching
the file .../linux-mainline-3.2/beagleboard/defconfig each time I make a change
and then re-build. It "seems to work" but I'm not totally convinced that
everything is in fact okay. Would you consider this an okay way to go or is
there something I've overlooked (or don't know!)?
Thanks.
