I can't get at my machines to test this myself (technically I'm still
on vacation), but when you
dump the bitbake environment, how many defconfig's show up in the
SRC_URI ? It would be
easy enough in your bbapend to simply call your defconfig something
else (i.e. defconfig-mine)
and override/append to kernel_do_configure() to simply copy yours over
top of the .config,
regardless of what the fetcher is doing with the SRC_URI.
