[Buildroot] Buildroot Not Using Saved Config for Linux

My apologies, I'm still very new at this so maybe this is just me, however, I'm still unable to get it to work.
To clarify, what your saying is that when I do "$ make BOARD=MYPROJECT" and there is a "local/MYPROJECT/linux-2.6.24.3.config", and the "BR2_PACKAGE_LINUX_KCONFIG" is set to ".//local/at91sam9261ek/linux-2.6.24.3.config". Then where it's actually looking for the linux config is:
"buildroot/local/MYPROJECT/local/MYPROJECT/linux-2.6.24.3.config"? Thus I have to do "$ make BOARD=at91sam9261ek getconfig" and then issue a "make"? I've just tried the following examples:
--Start From Scratch with using my local dir--
$ svn co svn://uclibc.org/trunk/buildroot -r 24237 buildroot
$ cd buildroot
$ cp -rap ../local/ local/
$ make menuconfig (SAVE EXIT)
$ make BOARD=MYPROJECT getconfig
$ make
--Result--
"buildroot/local/MYPROJECT/MYPROJECT.config" is used, however "buildroot/local/MYPROJECT/linux-2.6.24.3.config" is not used; it creates a brand new config based on the kernels at91sam9261ek_defconfig. This is how it acts even if I don't issue the "getconfig" command.
--Start With Linux Directory Already Extracted--
$ svn co svn://uclibc.org/trunk/buildroot -r 24237 buildroot
$ make menuconfig (SAVE EXIT)
$ make at91sam9261ek_defconfig
[[WAIT Till FINISH]]
$ make clean
$ rm -rf binaries
$ make linux26-menuconfig (DISABLE 16Bit NAND Flash Bus)
$ make saveconfig
$ make linux26-menuconfig (ENABLE 16Bit NAND Flash Bus)
$ make BOARD=MYPROJECT getconfig
$ make ALSO Tried $ make BOARD=MYPROJECT
--Result--
The "Enable 16Bit NAND Flash Bus" config is used, not the saved "Disable 16Bit NAND Flash Bus" config.

Aye, I did notice this. However, when I Issue a "make BOARD=MYPROJECT", for me, it does use the "buildroot/local/MYPROJECT/MYPROJECT.config", ignoring the "buildroot/.config" config.
> If you want to use the new board stuff, you have to do

Even after issuing this command, and doing "make" or "make BOARD=MYPROJECT', the linux config still isn't getting used properly.

Ahh I didn't know this. I only use the local directory inside the buildroot tree right now, however, it's good to know for the future. Thanks
