If the kernel is reasonable new then you can use that kernel and appropriate
.config, yes.

If you select Toolchain -> Kernel Headers -> Linux 2.6 snapshot then
a linux-2.6.tar.bz2 tarball is used which has to contain the kernel
sources in the "linux-2.6/" directory.

So, either you git clone git://kernel.org/.... linux-2.6
for an upstream kernel or you can
mv linux-kernel-2.6-from-vendor linux-2.6
# cd linux-2.6 && make mrproper
tar -cjf dl/linux-2.6.tar.bz2 linux-2.6
where "dl/" is the BR2_DL_DIR from your buildroot .config.
