Package is not broken. It is designed to install and activate kernel modules 
(while running) and to modify the kernel module boot load list so of course 
it "goes against" the running kernel. (which must be the same as the kernel 
pointed at by /usr/src/linux.

You should read
http://www.gentoo.org/doc/en/nvidia-guide.xml
and
http://gentoo-wiki.com/HOWTO_nVidia_Drivers
carefully.

You need to rebuild your kernel to eliminate the rivafb (rivafb obsolete on 
all gpu newer than riva128). And eliminate nvidiafb if you did that also. 
These two modules are documented as preventing proper function of 
nvidia-drivers. VESA VGA graphics support is the choice you should have for 
FB support.

Kernel Configuration

As mentioned above, the nVidia kernel driver installs and runs against your 
current kernel. It builds as a module, so it makes sense that your kernel 
must support the loading of kernel modules. If you used genkernel all to 
configure the kernel for you, then you're all set. If not, double check your 
kernel configuration so that this support is enabled:

      Code Listing 3.1: Enabling the Loading of Kernel Modules

Loadable module support --->
  [*] Enable loadable module support


You also need to enable Memory Type Range Register in your kernel:

      Code Listing 3.2: Enabling MTRR

Processor and Features --->
  [*] MTRR (Memory Type Range Register) support


Also, if you have an AGP graphics card, you can optionally enable agpgart 
support to your kernel, either compiled in or as a module. If you do not use 
the in-kernel agpgart, then the drivers will use their own agpgart 
implementation, called NvAGP. On certain systems, this performs better than 
the in-kernel agpgart, and on others, it performs worse. You will need to 
evaluate this on your own system to get the best performance. If you are 
unsure what to do, use the in-kernel agpgart:

      Code Listing 3.3: Enabling agpgart

Device Drivers --->
Character devices --->
<*> /dev/agpgart (AGP Support)

      Note: On amd64, the IOMMU controls the agpgart setting.


Arch-specific notes

      Important: For x86 and AMD64 processors, the in-kernel driver 
conflicts with the binary driver provided by nVidia. If you will be 
compiling your kernel for these CPUs, you must completely remove support for 
the in-kernel driver as shown:

      Code Listing 3.4: Remove the in-kernel driver

Device Drivers --->
Graphics Support --->
< >   nVidia Framebuffer Support
< >   nVidia Riva support


A good framebuffer alternative is VESA:

      Code Listing 3.5: Enable VESA support

Device Drivers --->
Graphics Support --->
<*>   VESA VGA graphics support
