[gentoo-user] Nvidia-drivers failing to install because kernel tree not found

I recently read an article at planet.gentoo.org about a 2 serious bugs
in the kernel that could lead to someone crashing or rooting a system
with linux kernels prior to gentoo-sources-2.6.23-r2. So being the
paranoid one that I am, I unmasked this ebuild and installed it. I
performed a `make oldconfig` and everything went well. I expected
Alsa-drivers and nvidia-drivers to be broken after the upgrade of the
kernel version. I symbolically linked "linux" to the new 2.6.24-r2
kernel source tree. Then, I proceed to re-emerge nvidia-drivers and it
states that it, for some odd reason, it cannot find the kernel source.
Moreover, it cannot even ascertain which system my kernel is built for
i686, Kryptonite 8 or K8 (Athlon). I tried changing versions of the
nvidia-drivers just incase the current stable one was not compatible
with the latest gentoo-sources package and the problem remained the
same. I wonder what's happening...Is there something that I could have
missed?
